1. The α and β subforms of aspartate aminotransferase were purified from pig heart. 2. The α subform contained 2mol of pyridoxal 5′-phosphate. The apo-(α subform) could be fully reactived by combination with 2mol of cofactor. 3. The protein fluorescence of the apo-(α subform) decreased non-linearly with increase in enzyme activity and concentration of bound cofactor. 4. It is concluded that the enzyme activity/mol of bound cofactor is largely independent of the number of cofactors bound to the dimer. 5. The β subform had approximately half the specific enzyme activity of the α subform, and contained an average of one active pyridoxal 5′-phosphate molecule per molecule, which could be removed by glutamate, and another inactive cofactor which could only be removed with NaOH. 6. On recombination with pyridoxal 5′-phosphate the protein fluorescence of the apo-(β subform) decreased linearly, showing that each dimeric enzyme molecule contained one active and one inactive bound cofactor. ...
This HMM describes a protein related to a number of pyridoxal phosphate-dependent enzymes, and in particular to selenocysteine synthase (SelA), which converts Ser to selenocysteine on its tRNA. While resembling SelA, this protein is found only in species that have a better candidate SelA or else lack the other genes (selB, selC, and selD) required for selenocysteine incorporation ...
Low vitamin B-6 status, based on plasma concentrations of pyridoxal-5-phosphate (PLP), has been identified in inflammatory diseases, including cardiovascular disease, rheumatoid arthritis, inflammatory bowel disease, and diabetes. Our objective was to examine the association between plasma PLP and multiple markers of inflammation in a community-based cohort [n = 2229 participants (55% women, mean age 61 ± 9 y)]. We created an overall inflammation score (IS) as the sum of standardized values of 13 individual inflammatory markers. Multivariable-adjusted regression analysis was used to assess the associations between the IS and plasma PLP. Geometric mean plasma PLP concentrations were lower in the highest tertile category of IS relative to the lowest (61 vs. 80 nmol/L; P-trend , 0.0001). Similarly, the prevalence of PLP insufficiency was significantly higher for participants in the highest compared with the lowest tertiles for IS categories. These relationships persisted after accounting for ...

In this case-control study nested in the MEC study, we found an inverse association between plasma PLP levels and colorectal cancer which was not explained by an association with plasma folate, seemed stronger at low levels of alcohol intake and among individuals with the MTHFR 677TT genotype, and was independent of plasma CRP levels. An inverse association with plasma folate was also observed, which seemed to be stronger among individuals with a low level of alcohol intake and was suggested among subjects with the MTHFR 677TT genotype.. Our findings for PLP are consistent with those of Wei et al. (5) who found a 52% reduction in colorectal cancer risk comparing the highest to the lowest quartile for plasma PLP (P trend = 0.07) in a nested case-control study in women. They are also consistent with those of Figueiredo et al. (6) who found an inverse association between baseline plasma PLP levels and recurrence of adenoma in a randomized trial of aspirin and folic acid supplementation. Similarly, ...
Background: Low plasma concentrations of pyridoxal 5-phosphate (PLP) are common in renal transplant recipients (RTRs) and confer increased risk of long-term mortality. To our knowledge, it is not known whether low plasma PLP concentrations have functional (i.e., intracellular) consequences and, if so, whether such consequences are associated with increased risk of mortality.Objectives: We assessed the association of plasma PLP with functional vitamin B-6 status and explored the potential association of functional vitamin B-6 status with long-term mortality in RTRs.Design: In a longitudinal cohort of 678 stable RTRs with a median follow-up of 5.3 y (IQR: 4.8-6.1 y) and 297 healthy controls, PLP, plasma 3-hydroxykynurenine (3-HK), and xanthurenic acid (XA) were analyzed via validated assays. PLP was used as direct biomarker for vitamin B-6 status, and the 3-HK:XA ratio was used as functional biomarker of vitamin B-6 status with a higher ratio reflecting worse functional vitamin B-6 ...

In this prospective, nested case-control study, we found that men with higher plasma PLP levels (above the median level) at baseline had a significantly lower risk of developing future colorectal cancer. The association was independent of conventional risk factors and plasma levels of biomarkers involved in one-carbon metabolism or inflammatory processes. The inverse association remained statistically significant after exclusion of cancer cases diagnosed during the first 4 years of follow-up, suggesting that the protective effect of PLP was unlikely to be influenced by preclinical disease or by change of diet.. We found a significant 51% lower risk of colorectal cancer among men in the highest quartiles than in the lowest quartiles of plasma PLP levels. Our findings in men are consistent with the previous findings in women (5), which observed a significant 52% reduction in colorectal cancer risk comparing the highest with the lowest quartiles (Ptrend = 0.07).

Vitamin B6 exists in three basic chemical forms: pyridoxine (an alcohol), pyridoxal (an aldehyde) and pyridoxamine (a primary amine). The three major forms can be phosphorylated at the 5-hydroxymethyl group. The first total synthesis of vitamin B6 was obtained by the condensation of acetylacetone and cyanacetamide. All living beings need vitamin B6 for their existence. However, only microorganisms and plants are able to synthesize it de novo. The role of vitamin B6 is related to a number of metabolic processes , and also plays a role like a cofactor in certain enzyme-catalyzed reactions. Vitamin B6 is essential for more than 100 enzymes involved in protein metabolism. The most studied coenzymic activity is one of the pytidoxal-5-phosfate (PLP), PLP-dependent enzymes are involved in important steps of amino acid metabolism, processes of decarboxylation and racemization, hemoglobin formation and chlorophyll biosynthesis. Vitamin B6 could have a role in preventing oxidative stress of the cells. A ...

Abstract: By mathematically analysing the curves of urinary excretion of vitamins, their plasma and erythrocytic concentrations or of TDP-effect, by constructing and mathematically interpreting the variation curves of distribution of a given plasma concentration of riboflavin and pyridoxal phosphate for 10-14-old-year children suffering from insulin-dependent diabetes mellitus after supplementation of vitamin, as a criterion of normal requirement for vitamin B2, the authors are prone to recommend the concentration of riboflavin over 10 micrograms/ml in plasma and over 96 micrograms/ml in erythrocytes, the hourly excretion of more than 27 micrograms. It has been ascertained that the criteria for the optimal bodys requirements for vitamins in diabetes mellitus children do not differ from those in healthy age-matched children. Thus, the value of TDP-effect is less than 1.25, the concentration of pyridoxal phosphate is over 8.4 micrograms/ml plasma, the excretion values of thiamine and 4-pyridoxic ...

Catalyzes the formation of pyridoxal 5-phosphate from ribose 5-phosphate (RBP), glyceraldehyde 3-phosphate (G3P) and ammonia. The ammonia is provided by the PdxT subunit. Can also use ribulose 5-phosphate and dihydroxyacetone phosphate as substrates, resulting from enzyme-catalyzed isomerization of RBP and G3P, respectively.
Catalyzes the hydrolysis of glutamine to glutamate and ammonia as part of the biosynthesis of pyridoxal 5-phosphate. The resulting ammonia molecule is channeled to the active site of PdxS.

Serine hydroxymethyltransferase from mammalian and bacterial sources is a pyridoxal-5-phosphate-containing enzyme, but the requirement of pyridoxal-5-phosphate for the activity of the enzyme from plant sources is not clear. The specific activity of serine hydroxymethyltransferase isolated from mung bean (Vigna radiata) seedlings in the presence and absence of pyridoxal-5-phosphate was comparable at every step of the purification procedure. The mung bean enzyme did not show the characteristic visible absorbance spectrum of pyridoxal-5-phosphate protein. Unlike the enzymes from sheep, monkey, and human liver, which were converted to the apoenzyme upon treatment with L-cysteine and dialysis, the mung bean enzyme similarly treated was fully active. Additional evidence in support of the suggestion that pyridoxal-5-phosphate may not be required for the mung bean enzyme was the observation that pencillamine, a well-known inhibitor of pyridoxal-5-phosphate enzymes, did not perturb the enzyme ...

Vitamin B6 is the collective term for a group of three related compounds, pyridoxine (PN), pyridoxal (PL) and pyridoxamine (PM), and their phosphorylated derivatives, pyridoxine 5-phosphate (PNP), pyridoxal 5-phosphate (PLP) and pyridoxamine 5-phosphate (PMP). Although all six of these compounds should technically be referred to as vitamin B6, the term vitamin B6 is commonly used interchangeably with just one of them, pyridoxine. Vitamin B6, principally in its biologically active coenzyme form pyridoxal 5-phosphate, is involved in a wide range of biochemical reactions, including the metabolism of amino acids and glycogen, the synthesis of nucleic acids, hemogloblin, sphingomyelin and other sphingolipids, and the synthesis of the neurotransmitters serotonin, dopamine, norepinephrine and gamma-aminobutyric acid (GABA ...

Background. The majority of patients receiving the platinum-based chemotherapy drug oxaliplatin develop peripheral neurotoxicity. Because this neurotoxicity involves ROS production, we investigated the efficacy of mangafodipir, a molecule that has antioxidant properties and is approved for use as an MRI contrast enhancer.. Methods. The effects of mangafodipir were examined in mice following treatment with oxaliplatin. Neurotoxicity, axon myelination, and advanced oxidized protein products (AOPPs) were monitored. In addition, we enrolled 23 cancer patients with grade ≥2 oxaliplatin-induced neuropathy in a phase II study, with 22 patients receiving i.v. mangafodipir following oxaliplatin. Neuropathic effects were monitored for up to 8 cycles of oxaliplatin and mangafodipir.. Results. Mangafodipir prevented motor and sensory dysfunction and demyelinating lesion formation. In mice, serum AOPPs decreased after 4 weeks of mangafodipir treatment. In 77% of patients treated with oxaliplatin and ...
