The propeptides of the vitamin K-dependent proteins possess different affinities for the vitamin K-dependent carboxylase. (1/225)

The vitamin K-dependent gamma-glutamyl carboxylase catalyzes the modification of specific glutamates in a number of proteins required for blood coagulation and associated with bone and calcium homeostasis. All known vitamin K-dependent proteins possess a conserved eighteen-amino acid propeptide sequence that is the primary binding site for the carboxylase. We compared the relative affinities of synthetic propeptides of nine human vitamin K-dependent proteins by determining the inhibition constants (Ki) toward a factor IX propeptide/gamma-carboxyglutamic acid domain substrate. The Ki values for six of the propeptides (factor X, matrix Gla protein, factor VII, factor IX, PRGP1, and protein S) were between 2-35 nM, with the factor X propeptide having the tightest affinity. In contrast, the inhibition constants for the propeptides of prothrombin and protein C are approximately 100-fold weaker than the factor X propeptide. The propeptide of bone Gla protein demonstrates severely impaired carboxylase binding with an inhibition constant of at least 200,000-fold weaker than the factor X propeptide. This study demonstrates that the affinities of the propeptides of the vitamin K-dependent proteins vary over a considerable range; this may have important physiological consequences in the levels of vitamin K-dependent proteins and the biochemical mechanism by which these substrates are modified by the carboxylase.  (+info)

Osteocalcin binds tightly to the gamma-glutamylcarboxylase at a site distinct from that of the other known vitamin K-dependent proteins. (2/225)

Vitamin K-dependent proteins contain a propeptide that is required for recognition by the enzyme gamma-glutamylcarboxylase. Substrates used in vitro for carboxylation studies lacking a prosequence are characterized by Km values in the millimolar range, whereas the Km for peptides containing a prosequence is three or four orders of magnitude smaller. Here we report that descarboxy-osteocalcin is an exception in this respect. With descarboxy-osteocalcin in purified propeptide-free recombinant carboxylase, the Km was 1.8 microM. Furthermore, osteocalcin was an inhibitor of descarboxy-osteocalcin carboxylation with a Ki of 76 microM. In contrast with the other vitamin K-dependent proteins, free propeptides do not inhibit descarboxy-osteocalcin carboxylation. Moreover, propeptide-containing substrates were inhibited neither by osteocalcin nor by its propeptide. From our studies we conclude that descarboxy-osteocalcin must have an internal recognition sequence that binds to gamma-glutamylcarboxylase at a site different from the propeptide-recognition site.  (+info)

Genetic and biochemical characterization of the alpha and beta components of a propionyl-CoA carboxylase complex of Streptomyces coelicolor A3(2). (3/225)

Two genes, accA1 and accA2, with nearly identical nucleotide sequences were cloned from Streptomyces coelicolor A3(2). The deduced amino acid sequences of the product of these two genes showed high similarity to BcpA2 of Saccharopolyspora erythraea and other biotin-containing proteins from different organisms assumed to be the alpha subunit of a propionyl-CoA carboxylase. A gene, pccB, encoding the carboxyl transferase subunit of this enzyme complex was also characterized. Strains disrupted in accA1 did not show any change in acetyl- or propionyl-CoA carboxylase activity, whilst cell-free extracts of a pccB mutant strain contained a reduced level of propionyl-CoA carboxylase. No mutants in accA2 could be isolated, suggesting that the gene may be essential. Heterologous expression of accA1, accA2 and pccB in Escherichia col and in vitro reconstitution of enzyme activity confirmed that PccB is the beta subunit of a propionyl-CoA carboxylase and that either AccA1 or AccA2 could act as the alpha component of this enzyme complex. The fact that accA2 mutants appear to be inviable suggests that this gene encodes a biotinylated protein that might be shared with other carboxyl transferases essential for the growth of S. coelicolor.  (+info)

Molecular characterization of the non-biotin-containing subunit of 3-methylcrotonyl-CoA carboxylase. (4/225)

The biotin enzyme, 3-methylcrotonyl-CoA carboxylase (MCCase) (3-methylcrotonyl-CoA:carbon-dioxide ligase (ADP-forming), EC 6.4.1. 4), catalyzes a pivotal reaction required for both leucine catabolism and isoprenoid metabolism. MCCase is a heteromeric enzyme composed of biotin-containing (MCC-A) and non-biotin-containing (MCC-B) subunits. Although the sequence of the MCC-A subunit was previously determined, the primary structure of the MCC-B subunit is unknown. Based upon sequences of biotin enzymes that use substrates structurally related to 3-methylcrotonyl-CoA, we isolated the MCC-B cDNA and gene of Arabidopsis. Antibodies directed against the bacterially produced recombinant protein encoded by the MCC-B cDNA react solely with the MCC-B subunit of the purified MCCase and inhibit MCCase activity. The primary structure of the MCC-B subunit shows the highest similarity to carboxyltransferase domains of biotin enzymes that use methyl-branched thiol esters as substrate or products. The single copy MCC-B gene of Arabidopsis is interrupted by nine introns. MCC-A and MCC-B mRNAs accumulate in all cell types and organs, with the highest accumulation occurring in rapidly growing and metabolically active tissues. In addition, these two mRNAs accumulate coordinately in an approximately equal molar ratio, and they each account for between 0.01 and 0.1 mol % of cellular mRNA. The sequence of the Arabidopsis MCC-B gene has enabled the identification of animal paralogous MCC-B cDNAs and genes, which may have an impact on the molecular understanding of the lethal inherited metabolic disorder methylcrotonylglyciuria.  (+info)

Identification of a Drosophila vitamin K-dependent gamma-glutamyl carboxylase. (5/225)

Using reduced vitamin K, oxygen, and carbon dioxide, gamma-glutamyl carboxylase post-translationally modifies certain glutamates by adding carbon dioxide to the gamma position of those amino acids. In vertebrates, the modification of glutamate residues of target proteins is facilitated by an interaction between a propeptide present on target proteins and the gamma-glutamyl carboxylase. Previously, the gastropod Conus was the only known invertebrate with a demonstrated vitamin K-dependent carboxylase. We report here the discovery of a gamma-glutamyl carboxylase in Drosophila. This Drosophila enzyme is remarkably similar in amino acid sequence to the known mammalian carboxylases; it has 33% sequence identity and 45% sequence similarity to human gamma-glutamyl carboxylase. The Drosophila carboxylase is vitamin K-dependent, and it has a K(m) toward a model pentapeptide substrate, FLEEL, of about 4 mm. However, unlike the human gamma-glutamyl carboxylase, it is not stimulated by human blood coagulation factor IX propeptides. We found the mRNA for Drosophila gamma-glutamyl carboxylase in virtually every embryonic and adult stage that we investigated, with the highest concentration evident in the adult head.  (+info)

An acyl-coenzyme A carboxylase encoding gene associated with jadomycin biosynthesis in Streptomyces venezuelae ISP5230. (6/225)

Analysis of a region of chromosomal DNA lying between jadR1 and jadI in the gene cluster for jadomycin biosynthesis in Streptomyces venezuelae ISP5230 detected an ORF encoding 584 amino acids similar in sequence to the biotin carboxylase (BC) and biotin carboxyl carrier protein (BCCP) components of acyl-coenzyme A carboxylases. Multiple sequence alignments of the deduced Jad protein with acyl-coenzyme A carboxylases from various sources located the BC and BCCP components in the N- and C-terminal regions, respectively, of the deduced polypeptides. The organization and amino acid sequence of the deduced polypeptide most closely resembled those in other Gram-positive bacteria broadly classified as actinomycetes. Disrupting the gene, designated jadJ, severely reduced but did not eliminate jadomycin production. The disruption had no effect on growth or morphology of the organism, implying that the product of jadJ is not essential for fatty acid biosynthesis. It is concluded that jadJ supplies malonyl-coenzyme A for biosynthesis of the polyketide intermediate that is eventually processed to form the antibiotic jadomycin B.  (+info)

A conserved motif within the vitamin K-dependent carboxylase gene is widely distributed across animal phyla. (7/225)

The vitamin K-dependent gamma-glutamyl carboxylase catalyzes the posttranslational conversion of glutamic acid to gamma-carboxyglutamic acid, an amino acid critical to the function of the vitamin K-dependent blood coagulation proteins. Given the functional similarity of mammalian vitamin K-dependent carboxylases and the vitamin K-dependent carboxylase from Conus textile, a marine invertebrate, we hypothesized that structurally conserved regions would identify sequences critical to this common functionality. Furthermore, we examined the diversity of animal species that maintain vitamin K-dependent carboxylation to generate gamma-carboxyglutamic acid. We have cloned carboxylase homologs in full-length or partial form from the beluga whale (Delphinapterus leucas), toadfish (Opsanus tau), chicken (Gallus gallus), hagfish (Myxine glutinosa), horseshoe crab (Limulus polyphemus), and cone snail (Conus textile) to compare these structures to the known bovine, human, rat, and mouse cDNA sequences. Comparison of the predicted amino acid sequences identified a nearly perfectly conserved 38-amino acid residue region in all of these putative carboxylases. In addition, this amino acid motif is also present in the Drosophila genome and identified a Drosophila homolog of the gamma-carboxylase. Assay of hagfish liver demonstrated vitamin K-dependent carboxylase activity in this hemichordate. These results demonstrate the broad distribution of the vitamin K-dependent carboxylase gene, including a highly conserved motif that is likely critical for enzyme function. The vitamin K-dependent biosynthesis of gamma-carboxyglutamic acid appears to be a highly conserved function in the animal kingdom.  (+info)

A topological study of the human gamma-glutamyl carboxylase. (8/225)

gamma-Glutamyl carboxylase (GC), a polytopic membrane protein found in the endoplasmic reticulum (ER), catalyzes vitamin K-dependent posttranslational modification of glutamate to gamma-carboxyl glutamate. In an attempt to delineate the structure of this important enzyme, in vitro translation and in vivo mapping were used to study its membrane topology. Using terminus-tagged full-length carboxylase, expressed in 293 cells, it was demonstrated that the amino-terminus of the GC is on the cytoplasmic side of the ER, while the carboxyl-terminus is on the lumenal side. In addition, a series of fusions were made to encode each predicted transmembrane domain (TMD) followed by a leader peptidase (Lep) reporter tag, as analyzed by the computer algorithm TOPPRED II. Following in vitro translation of each fusion in the presence of canine microsomes, the topological orientation of the Lep tag was determined by proteinase K digestion and endoglycosidase H (Endo H) cleavage. From the topological orientation of the Lep tag in each fusion, the GC spans the ER membrane at least 5 times, with its N-terminus in the cytoplasm and its C-terminus in the lumen.  (+info)

3-Methylcrotonyl-CoA carboxylase deficiency (MCCC2-related) is a pan-ethnic, autosomal recessive disease caused by pathogenic variants in the MCCC2 gene. These variants impair the ability of the enzyme 3-methylcrotonyl-CoA carboxylase to break down proteins that contain the amino acid leucine. Presentation in childhood or early infancy is characterized by feeding difficulties, vomiting and diarrhea, excessive fatigue, and hypotonia. If detected early, the condition can be managed with a low-protein diet. If untreated, this disorder can eventually cause developmental delay, seizures, and coma. However, most individuals with this condition remain asymptomatic into adulthood. Life expectancy depends on the severity of presentation. No clear genotype-phenotype correlation has been noted..

Vitamin K1 2,3-epoxide (CAS: 25486-55-9) is a vitamin K derivative. Vitamin K is needed for the posttranslational modification of certain proteins, mostly required for blood coagulation. Within the cell, vitamin K undergoes electron reduction to a reduced form of vitamin K (called vitamin K hydroquinone) by the enzyme vitamin K epoxide reductase (or VKOR). Another enzyme then oxidizes vitamin K hydroquinone to allow carboxylation of glutamate into gamma-carboxyglutamate (Gla). This enzyme is called the gamma-glutamyl carboxylase or the vitamin K-dependent carboxylase. The carboxylation reaction will only proceed if the carboxylase enzyme is able to oxidize vitamin K hydroquinone into vitamin K epoxide at the same time; the carboxylation and epoxidation reactions are said to be coupled reactions. Vitamin K epoxide is then re-converted into vitamin K by the vitamin K epoxide reductase. These two enzymes comprise the so-called vitamin K cycle. One of the reasons why vitamin K is rarely deficient in ...
Regulation of the expression of the gene(s) coding for the 78-kD, biotin-containing subunit of [beta]-methylcrotonyl-coenzyme A carboxylase (MCCase) was investigated in different organs of tomato (Lycopersicon esculantus) plants. The specific activity of MCCase is highest in extracts from roots, followed in descending order by ripe and ripening fruits, stems, and leaves. The specific activity is 10-fold higher in roots than in leaves. However, the steady-state levels of the 78-kD subunit of MCCase and its mRNA are approximately equal in both roots and leaves. Instead, the difference in MCCase activity between these two organs is directly correlated to the biotinylation status of the enzymes biotin-containing subunit. Thus, the lower activity of MCCase in leaves is attributed to the reduced biotinylation of the biotin-containing subunit of the enzyme. Consistent with this model, a pool of nonbiotinylated enzyme is present in leaves, whereas the nonbiotinylated enzyme is undetectable in roots. ...

3-Hydroxyisovalerylcarnitine is structual derivative of 3-hydroxyisovaleric acid and carnitine. Due to its increased concentration in blood, 3-hydroxyisovalerylcarnitine (C5OH-I) is an important indicator for the diagnosis of organic acidemias in newborns (PMID: 18088573 ). Analysis of acylcarnitines by tandem mass spectrometry (MS/MS) has recently been used to screen newborns for organic acidemias and fatty acid oxidation defects (PMID: 7494654 , 9216448 , 11427446 , 12127323 , 14578311 ). These diseases cause the accumulation of acyl-CoA, which is esterified to acylcarnitine by carnitine acyltransferase. Acylcarnitine is then eliminated in the urine, thus acylcarnitine concentration serves as an excellent indicator for these diseases (PMID: 6361812 ). 3-Hydroxyisovalerylcarnitine (C5OH-I) is an indicator for diagnoses of multiple carboxylase deficiency (MCD), 3-methylcrotonyl-CoA carboxylase deficiency and 3-hydroxy-3-methylglutaryl-CoA lyase deficiency (PMID: 18088573 ), which are inborn ...
There is much debate as to the clinical significance of 3-methylcrotonyl-CoA carboxylase deficiency (3MCC deficiency). In thinking about this issue, I recently read a paper by Arnold et al, (Mol Genet Metab. 2012 Aug;106(4):439-41) that describes their retrospective analysis of 35 cases of 3-MCC deficiency identified by newborn screening and confirmed by enzyme and/or molecular analysis.

The first committed step of fatty acid and polyketides biosynthesis, the biotin-dependent carboxylation of an acyl-CoA, is catalyzed by acyl-CoA carboxylases (ACCases) such as acetyl-CoA carboxylase (ACC) and propionyl-CoA carboxylase (PCC). ACC and PCC in Streptomyces coelicolor are homologues multisubunit complexes that can carboxylate different short chain acyl-CoAs. While ACC is able to carboxylate acetyl-, propionyl-, or butyryl-CoA with approximately the same specificity, PCC only recognizes propionyl- and butyryl-CoA as substrates. How ACC and PCC have such different specificities towards these substrates is only partially understood. To further understand the molecular basis of how the active site residues can modulate the substrate recognition, we mutated D422, N80, R456 and R457 of PccB, the catalytic beta subunit of PCC. The crystal structures of six PccB mutants and the wild type crystal structure were compared systematically to establish the sequence-structure-function relationship ...

New technology enables expansion of newborn screening (NBS) of inborn errors aimed to prevent adverse outcome. In conditions with a large share of asymptomatic phenotypes, the potential harm created by NBS must carefully be weighed against benefit. Policies vary throughout the United States, Australia, and Europe due to limited data on outcome and treatability of candidate screening conditions. We elaborated the rationale for decision making in 3-methylcrotonyl-coenzyme A (CoA) carboxylase deficiency (MCCD), which afflicts leucine catabolism, with reported outcomes ranging from asymptomatic to death. In Bavaria, we screened 677,852 neonates for 25 conditions, including MCCD, based on elevated concentrations of 3-hydroxyisovalerylcarnitine (3-HIVA-C). Genotypes of MCCA (MCCC1) and MCCB (MCCC2) were assessed in identified newborns, their relatives, and in individuals (n = 17) from other regions, and correlated to biochemical and clinical phenotypes. NBS revealed eight newborns and six relatives ...
In the light of the structure-based comparisons identifying the PfSUB1 prodomain Prodp9 as the best template for SUB1-ProM, we further examined the predicted structural similarities between these proteins. Like other subtilisins, immediately following cleavage at the propeptide-catalytic domain junction, the propeptides of PfSUB1 and PvSUB1 remain tightly bound to their cognate catalytic domain, primarily through interactions between the beta sheet of the propeptide and two prominent surface-located parallel alpha helices of the catalytic domain [14,41]. In the case of PfSUB1, key contributions to propeptide binding include hydrophobic interactions with the sidechain of Ile178, located at the beta hairpin turn linking two strands of the Prodp9 beta sheet, which plugs into a hydrophobic pocket on the catalytic domain surface (Figure 5a and Supplementary Figure S5a). Interestingly, Prodp9 Ile178 is replaced by a Leu residue (Leu115) in SUB1-ProM, the sidechain of which could be accommodated in the ...

The peptide substrate commonly used in vitamin K-dependent carboxylation, Phe-Leu-Glu-Glu-Val, has been shown, by the use of high-voltage paper electrophoresis, to be degraded from the N-terminus by a microsomal leucine amino-peptidase. The replacement of phenylalanine with a N-t-butoxycarbonyl group resulted in a tetrapeptide substrate with a blocked N-terminus resistant to enzymic degradation. Vitamin K-dependent carboxylation of this non-degradable substrate gave a unique carboxylated product, which was separated from microsomal protein and unchanged substrate by using DEAE-Sephadex A25 as a final step. The carboxylated product was subsequently decarboxylated in 2HCl and analysed by using g.l.c. coupled to a mass spectrometer. This showed that only the first glutamic acid residue in the peptide substrate was carboxylated. ...

Protein C is a precursor of plasma serine proteinases, and its active form inactivates specifically blood coagulation Factor V and Factor VIII. Since a specific and sensitive synthetic substrate for the activated protein C was not known, we studied its amidolytic activity toward 25 fluorogenic peptides of the type peptidyl-4-methylcoumaryl-7-amide (peptidyl MCA). The activated protein C, namely, bovine protein C activated by bovine alpha-thrombin, showed the highest activity toward Boc-Leu-Ser-Thr-Arg-MCA. The enzymes Km and Kcat values for this substrate were calculated to be 3.3 x 10(-4) M and 8.4 s-1, respectively. Optimum conditions for measurement of activated protein C activity were studied with this substrate. Optimum pH was 8.5. For the maximum activity at pH 8.5, concentrations of 0.1 M NaCl and 1 mM CaCl2 had to be maintained in the reaction mixture. The fluorogenic peptide Boc-Leu-Ser-Thr-Arg-MCA was successfully applied to a simple and accurate assay of protein C during its ...
Matrix gla protein (MGP) is member of a family of vitamin-K2 dependent, Gla-containing proteins. MGP has a high affinity binding to calcium ions, similar to other Gla-containing proteins. The protein acts as an inhibitor of vascular mineralization and plays a role in bone organization. MGP is found in number body tissues in mammals, birds, and fish. Its mRNA is present in bone, cartilage, heart, and kidney. It is present in bone together with the related vitamin K2-dependent protein osteocalcin. In bone, its production is increased by vitamin D. The MGP was linked to the short arm of chromosome 12 in 1990. Its mRNA sequence length is 585 bases long in humans. MGP and osteocalcin are both calcium-binding proteins that may participate in the organisation of bone tissue. Both have glutamate residues that are post-translationally carboxylated by the enzyme gamma-glutamyl carboxylase in a reaction that requires Vitamin K hydroquinone. This process also occurs with a number of proteins involved in ...

Hereditary combined vitamin K-dependent clotting factors deficiency (VKCFD) is a rare congenital bleeding disorder resulting from variably decreased levels of coagulation factors II, VII, IX and X as well as natural anticoagulants protein C, protein S and protein Z. The spectrum of bleeding symptoms ranges from mild to severe with onset in the neonatal period in severe cases. The bleeding symptoms are often life-threatening, occur both spontaneously and in a surgical setting, and usually involve the skin and mucosae. A range of non-haemostatic symptoms are often present, including developmental and skeletal anomalies. VKCFD is an autosomal recessive disorder caused by mutations in the genes of either gamma-glutamyl carboxylase or vitamin K2,3-epoxide reductase complex. These two proteins are necessary for gamma-carboxylation, a post-synthetic modification that allows coagulation proteins to display their proper function. The developmental and skeletal anomalies seen in VKCFD are the result of defective
Promotes healthy glucose metabolism and nerve health; helps support healthy nails Biotin is a water-soluble B vitamin that is an essential co-factor for a number of metabolic carboxylation reactions. Biotin forms a covalent bond to the following carboxylase enzymes: pyruvate carboxylase for glucose metabolism, acetyl CoA carboxylase for fatty acid oxidation, and propionyl-CoA carboxylase and methylcrotonyl-CoA carboxylase for amino acid metabolism. A clinical study reported that high dose administration of biotin helped promote healthy glucose metabolism. A number of animal studies support this claim. Biotin may also act to promote transcription and translation of glucokinase, an enzyme found in the liver and pancreas that participates in the metabolism of glucose to form glycogen. Studies have also indicated that biotin is supportive of nervous system health and function. A clinical study revealed that biotin promotes nerve cell health. In addition, a double-blind study reported that biotin
WHAT DOES BIOTIN DO FOR US ?. 1. Carboxyle enzymes:. - The first one, Acetyl-CoA carboxylase, starts the process for creating fatty acids. Most of us want beautiful shiny hair and strong healthy fingernails. Biotin is involved in the creation of fatty acids. One group of fatty acids called phospholipids is a necessary part of the structure of cell membranes including those which make up our hair and nails.. - The second one, Pyruvate carboxylase is critical for the process called gluconeogenesis. Gluconeogenesis is the process which creates glucose out of fats and amino acids to use for energy when the body cant get it from carbohydrates. Those low or no carb diets weve all heard about or perhaps have tried, start the process of gluconeogenesis. The fat stores in our bodies and unfortunately some of the proteins we eat are used for energy instead of the carbohydrates we would ordinarily consume.. - The third one, Methylcrotonyl-CoA carboxylase is used in the creation of energy from the ...

A vitamin K-dependent carboxylation converts glutamate residues on prothrombin, which are weak chelators of Ca2+, into gamma-carboxyglutamate, a much stronger chelator. The binding of Ca2+ by prothrombin anchors it to the phospholipid membranes derived from blood platlets following injury. This binding of prothrombin brings it into close contact with two enzymes which regulate its conversion into thrombin, which can then activate fibrinogen in the plasma to fill the breach.. Sources:. Vitamin K is found in green leafy vegetables.. Fascinating Fact: To prevent excessive clotting after an operation the vitamin K antagonist, Warfarin (rat poison) is administered in carefully controlled doses.. ...

Paracetamol is recommended as a first-line analgesic and antipyretic therapy in patients receiving short- and long-term oral anticoagulation, especially elderly patient.However,Increased INR was previously observed in patients treated with warfarin and paracetamol given at the maximum recommended dose (4g/day).. To date, the mechanism of this interaction has not been determined.A recent in vitro study suggested that the toxic metabolite N-acetyl-para-benzoquinoneimine (NAPQI) appeared to interfere with vitamin K-dependent γ-carboxylase (VKD-carb) and vitamin K epoxide reductase (VKOR) activites12. The question remaining to be dealt with is whether this in vitro observation can explain the in vivo paracetamol-warfarin interaction. We aim to evaluate the effect of paracetamol at the most widely used doses 2 and 3g/day on INR in stable patients treated with warfarin in a double blind randomized placebo-controlled trial and to identify the mechanism involved in this interaction in vivo. ...

endoplasmic reticulum sites of Gla protein synthesis. In the case of the blood coagulation proteins, the sole site of synthesis is the liver. Each carboxylated protein has a C-terminal propeptide sequence that binds the carboxylase enzyme, and directs a coordinated series of carboxylations of the recipient gluta-myl residues, before the propeptide is removed and the fully carboxylated protein is then secreted into the extracellular space for transport into the plasma.. Vitamin K acts as the essential recycling cofactor (or cosubstrate) for all protein carboxylation, Gla-forming reactions (Figure 3). In its dihydro or quinol form, the vitamin reacts with molecular oxygen, thereby creating a highly reactive, high-energy carba-nion at the Glu site for insertion of carbon dioxide, creating a new Gla residue. This vitamin K quinol oxidation step provides the essential energy for the endothermic carboxylation step. The other product of the reaction is the epoxide of vitamin K, comprising a ...

Coagulation. Coagulation results in the generation of thrombin, which converts soluble fibrinogen to fibrin. Coagulation occurs through the action of discrete enzyme complexes, which are composed of a vitamin K-dependent enzyme and a non-enzyme cofactor, and assemble on anionic phospholipid membranes in a calcium-dependent fashion. Each enzyme complex activates a vitamin K-dependent substrate that becomes the enzyme component of the subsequent complex. Together, these complexes generate a small amount of thrombin, which amplifies its own generation by activating the non-enzyme cofactors and platelets, which then provide an anionic surface on which the complexes assemble. The three enzyme complexes involved in thrombin generation are extrinsic tenase, intrinsic tenase, and prothrombinase. Although extrinsic tenase initiates the system under most circumstances, the contact system also plays a role in some situations.. Extrinsic Tenase (FVIIa-TF complex). This complex forms upon exposure of tissue ...

Research demonstrates that children are the most deficient of the essential nutrient vitamin K2, creating serious skeletal and vascular implications for growing bodies. Fortunately, there is a simple, proven solution: studies have shown that supplementation with 45-50 mcg of vitamin K2 as MK-7 daily supports bone mineral density, reduces fractures, and may contribute toward cardiovascular health in children - laying the strong foundation for their transition from adolescence into adulthood.. Vitamin K is actually a group of fat-soluble vitamins. It was first recognized for its essential role in the functioning of several proteins involved in blood clotting or coagulation, which is important to prevent excessive bleeding after an injury. In fact, the K in vitamin K is derived from the German word koagulation. Now, vitamin K is understood to offer additional benefits, including its role activating vitamin K-dependent proteins that are necessary for bone mineralization (e.g., helping to keep ...
