Product of the oxidation of ethanol and of the destructive distillation of wood. It is used locally, occasionally internally, as a counterirritant and also as a reagent. (Stedman, 26th ed)
An intracellular signaling system involving the MAP kinase cascades (three-membered protein kinase cascades). Various upstream activators, which act in response to extracellular stimuli, trigger the cascades by activating the first member of a cascade, MAP KINASE KINASE KINASES; (MAPKKKs). Activated MAPKKKs phosphorylate MITOGEN-ACTIVATED PROTEIN KINASE KINASES which in turn phosphorylate the MITOGEN-ACTIVATED PROTEIN KINASES; (MAPKs). The MAPKs then act on various downstream targets to affect gene expression. In mammals, there are several distinct MAP kinase pathways including the ERK (extracellular signal-regulated kinase) pathway, the SAPK/JNK (stress-activated protein kinase/c-jun kinase) pathway, and the p38 kinase pathway. There is some sharing of components among the pathways depending on which stimulus originates activation of the cascade.

Purification and characterization of two extremely thermostable enzymes, phosphate acetyltransferase and acetate kinase, from the hyperthermophilic eubacterium Thermotoga maritima. (1/86)

Phosphate acetyltransferase (PTA) and acetate kinase (AK) of the hyperthermophilic eubacterium Thermotoga maritima have been purified 1,500- and 250-fold, respectively, to apparent homogeneity. PTA had an apparent molecular mass of 170 kDa and was composed of one subunit with a molecular mass of 34 kDa, suggesting a homotetramer (alpha4) structure. The N-terminal amino acid sequence showed significant identity to that of phosphate butyryltransferases from Clostridium acetobutylicum rather than to those of known phosphate acetyltransferases. The kinetic constants of the reversible enzyme reaction (acetyl-CoA + Pi -->/<-- acetyl phosphate + CoA) were determined at the pH optimum of pH 6.5. The apparent Km values for acetyl-CoA, Pi, acetyl phosphate, and coenzyme A (CoA) were 23, 110, 24, and 30 microM, respectively; the apparent Vmax values (at 55 degrees C) were 260 U/mg (acetyl phosphate formation) and 570 U/mg (acetyl-CoA formation). In addition to acetyl-CoA (100%), the enzyme accepted propionyl-CoA (60%) and butyryl-CoA (30%). The enzyme had a temperature optimum at 90 degrees C and was not inactivated by heat upon incubation at 80 degrees C for more than 2 h. AK had an apparent molecular mass of 90 kDa and consisted of one 44-kDa subunit, indicating a homodimer (alpha2) structure. The N-terminal amino acid sequence showed significant similarity to those of all known acetate kinases from eubacteria as well that of the archaeon Methanosarcina thermophila. The kinetic constants of the reversible enzyme reaction (acetyl phosphate + ADP -->/<-- acetate + ATP) were determined at the pH optimum of pH 7.0. The apparent Km values for acetyl phosphate, ADP, acetate, and ATP were 0.44, 3, 40, and 0.7 mM, respectively; the apparent Vmax values (at 50 degrees C) were 2,600 U/mg (acetate formation) and 1,800 U/mg (acetyl phosphate formation). AK phosphorylated propionate (54%) in addition to acetate (100%) and used GTP (100%), ITP (163%), UTP (56%), and CTP (21%) as phosphoryl donors in addition to ATP (100%). Divalent cations were required for activity, with Mn2+ and Mg2+ being most effective. The enzyme had a temperature optimum at 90 degrees C and was stabilized against heat inactivation by salts. In the presence of (NH4)2SO4 (1 M), which was most effective, the enzyme did not lose activity upon incubation at 100 degrees C for 3 h. The temperature optimum at 90 degrees C and the high thermostability of both PTA and AK are in accordance with their physiological function under hyperthermophilic conditions.  (+info)

Cloning, sequence analysis, expression and inactivation of the Corynebacterium glutamicum pta-ack operon encoding phosphotransacetylase and acetate kinase. (2/86)

The Corynebacterium glutamicum ack and pta genes encoding the acetate-activating enzymes acetate kinase and phosphotransacetylase were isolated, subcloned on a plasmid and re-introduced into Corynebacterium glutamicum. Relative to the wild-type, the recombinant strains showed about tenfold higher specific activities of both enzymes. Sequence analysis of a 3657 bp DNA fragment revealed that the ack and pta genes are contiguous in the corynebacterial chromosome, with pta upstream and the last nucleotide of the pta stop codon (TAA) overlapping the first of the ack start codon (ATG). The predicted gene product of pta consists of 329 amino acids (Mr 35242), that of ack consists of 397 amino acids (Mr 43098) and the amino acid sequences of the two polypeptides show up to 60 % (phosphotransacetylase) and 53% (acetate kinase) identity in comparison with respective enzymes from other organisms. Northern (RNA) blot hybridizations using pta- and ack-specific probes and transcriptional cat fusion experiments revealed that the two genes are transcribed as a 2.5 kb bicistronic mRNA and that the expression of this operon is induced when Corynebacterium glutamicum grows on acetate instead of glucose as a carbon source. Directed inactivation of the chromosomal pta and ack genes led to the absence of detectable phosphotransacetylase and acetate kinase activity in the respective mutants and to their inability to grow on acetate. These data indicate that no isoenzymes of acetate kinase and phosphotransacetylase are present in Corynebacterium glutamicum and that a functional acetate kinase/phosphotransacetylase pathway is essential for growth of this organism on acetate.  (+info)

Genes coding for phosphotransacetylase and acetate kinase in Sinorhizobium meliloti are in an operon that is inducible by phosphate stress and controlled by phoB. (3/86)

Recent work in this laboratory has shown that the gene coding for acetate kinase (ackA) in Sinorhizobium meliloti is up-regulated in response to phosphate limitation. Characterization of the region surrounding ackA revealed that it is adjacent to pta, which codes for phosphotransacetylase, and that these two genes are part of an operon composed of at least two additional genes in the following order: an open reading frame (orfA), pta, ackA, and the partial sequence of a gene with an inferred peptide that has a high degree of homology to enoyl-ACP reductase (fabI). Experiments combining enzyme assays, a chromosomal lacZ::ackA transcriptional fusion, complementation analysis with cosmid subclones, and the creation of mutations in pta and ackA all indicated that the orfA-pta-ackA-fabI genes are cotranscribed in response to phosphate starvation. Primer extension was used to map the position of the phosphate starvation-inducible transcriptional start sites upstream of orfA. The start sites were found to be preceded by a sequence having similarity to PHO boxes from other phosphate-regulated genes in S. meliloti and to the consensus PHO box in Escherichia coli. Introduction of a phoB mutation in the wild-type strain eliminated elevated levels of acetate kinase and phosphotransacetylase activities in response to phosphate limitation and also eliminated the phosphate stress-induced up-regulation of the ackA::lacZ fusion. Mutations in either ackA alone or both pta and ackA did not affect the nodulation or nitrogen fixation phenotype of S. meliloti.  (+info)

Homofermentative production of D- or L-lactate in metabolically engineered Escherichia coli RR1. (4/86)

We investigated metabolic engineering of fermentation pathways in Escherichia coli for production of optically pure D- or L-lactate. Several pta mutant strains were examined, and a pta mutant of E. coli RR1 which was deficient in the phosphotransacetylase of the Pta-AckA pathway was found to metabolize glucose to D-lactate and to produce a small amount of succinate by-product under anaerobic conditions. An additional mutation in ppc made the mutant produce D-lactate like a homofermentative lactic acid bacterium. When the pta ppc double mutant was grown to higher biomass concentrations under aerobic conditions before it shifted to the anaerobic phase of D-lactate production, more than 62.2 g of D-lactate per liter was produced in 60 h, and the volumetric productivity was 1.04 g/liter/h. To examine whether the blocked acetate flux could be reoriented to a nonindigenous L-lactate pathway, an L-lactate dehydrogenase gene from Lactobacillus casei was introduced into a pta ldhA strain which lacked phosphotransacetylase and D-lactate dehydrogenase. This recombinant strain was able to metabolize glucose to L-lactate as the major fermentation product, and up to 45 g of L-lactate per liter was produced in 67 h. These results demonstrate that the central fermentation metabolism of E. coli can be reoriented to the production of D-lactate, an indigenous fermentation product, or to the production of L-lactate, a nonindigenous fermentation product.  (+info)

Characterization of a group of anaerobically induced, fnr-dependent genes of Salmonella typhimurium. (5/86)

We have previously reported the isolation of a group of anaerobically regulated, fnr-dependent lac fusions in Salmonella typhimurium and have grouped these oxd genes into classes based on map position. In order to identify these genes, we have replaced the original Mud-lac fusion in a member of each oxd class with the much smaller Mud-cam element, cloned the fusion, and determined DNA sequence sufficient to define the oxd gene. Several of the fusions correspond to previously known genes from S. typhimurium or Escherichia coli: oxd-4 = cbiA and oxd-11 = cbiK, oxd-5 = hybB, oxd-7 = dcuB, oxd-8 = moaB, oxd-12 = dmsA, and oxd-14 = napB (aeg-46. 5). Two other fusions correspond to previously unknown loci: oxd-2 encodes an acetate/propionate kinase, and oxd-6 encodes a putative ABC transporter present in S. typhimurium but not in E. coli.  (+info)

Catabolite regulation of the pta gene as part of carbon flow pathways in Bacillus subtilis. (6/86)

In Bacillus subtilis, the products of the pta and ackA genes, phosphotransacetylase and acetate kinase, play a crucial role in the production of acetate, one of the most abundant by-products of carbon metabolism in this gram-positive bacterium. Although these two enzymes are part of the same pathway, only mutants with inactivated ackA did not grow in the presence of glucose. Inactivation of pta had only a weak inhibitory effect on growth. In contrast to pta and ackA in Escherichia coli, the corresponding B. subtilis genes are not cotranscribed. Expression of the pta gene was increased in the presence of glucose, as has been reported for ackA. The effects of the predicted cis-acting catabolite response element (CRE) located upstream from the promoter and of the trans-acting proteins CcpA, HPr, Crh, and HPr kinase on the catabolite regulation of pta were investigated. As for ackA, glucose activation was abolished in ccpA and hprK mutants and in the ptsH1 crh double mutant. Footprinting experiments demonstrated an interaction between CcpA and the pta CRE sequence, which is almost identical to the proposed CRE consensus sequence. This interaction occurs only in the presence of Ser-46-phosphorylated HPr (HPrSer-P) or Ser-46-phosphorylated Crh (CrhSer-P) and fructose-1,6-bisphosphate (FBP). In addition to CcpA, carbon catabolite activation of the pta gene therefore requires at least two other cofactors, FBP and either HPr or Crh, phosphorylated at Ser-46 by the ATP-dependent Hpr kinase.  (+info)

The role of histidines in the acetate kinase from Methanosarcina thermophila. (7/86)

The role of histidine in the catalytic mechanism of acetate kinase from Methanosarcina thermophila was investigated by diethylpyrocarbonate inactivation and site-directed mutagenesis. Inactivation was accompanied by an increase in absorbance at 240 nm with no change in absorbance at 280 nm, and treatment of the inactivated enzyme with hydroxylamine restored 95% activity, results that indicated diethylpyrocarbonate inactivates the enzyme by the specific modification of histidine. The substrates ATP, ADP, acetate, and acetyl phosphate protected against inactivation suggesting at least one active site where histidine is modified. Correlation of residual activity with the number of histidines modified, as determined by absorbance at 240 nm, indicated that a maximum of three histidines are modified per subunit, two of which are essential for full inactivation. Comparison of the M. thermophila acetate kinase sequence with 56 putative acetate kinase sequences revealed eight highly conserved histidines, three of which (His-123, His-180, and His-208) are perfectly conserved. Diethylpyrocarbonate inactivation of the eight histidine --> alanine variants indicated that His-180 and His-123 are in the active site and that the modification of both is necessary for full inactivation. Kinetic analyses of the eight variants showed that no other histidines are important for activity. Analysis of additional His-180 variants indicated that phosphorylation of His-180 is not essential for catalysis. Possible functions of His-180 are discussed.  (+info)

Urkinase: structure of acetate kinase, a member of the ASKHA superfamily of phosphotransferases. (8/86)

Acetate kinase, an enzyme widely distributed in the Bacteria and Archaea domains, catalyzes the phosphorylation of acetate. We have determined the three-dimensional structure of Methanosarcina thermophila acetate kinase bound to ADP through crystallography. As we previously predicted, acetate kinase contains a core fold that is topologically identical to that of the ADP-binding domains of glycerol kinase, hexokinase, the 70-kDa heat shock cognate (Hsc70), and actin. Numerous charged active-site residues are conserved within acetate kinases, but few are conserved within the phosphotransferase superfamily. The identity of the points of insertion of polypeptide segments into the core fold of the superfamily members indicates that the insertions existed in the common ancestor of the phosphotransferases. Another remarkable shared feature is the unusual, epsilon conformation of the residue that directly precedes a conserved glycine residue (Gly-331 in acetate kinase) that binds the alpha-phosphate of ADP. Structural, biochemical, and geochemical considerations indicate that an acetate kinase may be the ancestral enzyme of the ASKHA (acetate and sugar kinases/Hsc70/actin) superfamily of phosphotransferases.  (+info)

The acetate kinase variants reported here all exhibited severalfold increases in the Km for acetate, supporting the hypothesized roles for the hydrophobic pocket residues Val93, Leu122, Phe179, and Pro232 as important contributors to acetate binding. The progressive increase in Km for acetate with a decrease in the side chain volume at position 93 supports the hypothesis that there is a decrease in hydrophobic interactions with acetate as the pocket size increases. Furthermore, the overall hydrophobicity of the pocket is decreased in the variants. Attempts to measure the Kd values of the variants for acetate and acetyl phosphate have been unsuccessful so far due to the upper solubility limit of acetate kinase (20 μM) relative to the Km values of the variants for acetate and acetyl phosphate, which were as high as 39.5 and 1.19 mM, respectively. The recently reported crystal structure of acetate kinase from M. thermophila containing acetate shows the methyl group located in the hydrophobic ...

Cloning of Clostridium thermocellum acetate kinase (ack) and/or phosphotransacetylase (pta) genes in Escherichia coli by functional complementation of ack and/or pta mutants was complicated by an alternative acetate assimilation pathway involving acetyl-CoA synthetase (ACS). In addition to the problems encountered with the complementation approach, cloning of these genes was not readily achieved using heterologous probing with corresponding genes from Escherichia coli and Methanosarcina thermophila due to the lack of sufficient homology. The use of a PCR-based approach, on the other hand, yielded a specific C. Thermocellum gene fragment which showed significant sequence identity to the ack gene for which primers were designed. The subcloned ack fragment was then successfully used as a probe for the isolation of the corresponding gene and restriction analysis of that region.

Extracellular fatty acid incorporation into the phospholipids of Staphylococcus aureus occurs via fatty acid phosphorylation. We show that fatty acid kinase (Fak) is composed of two dissociable protein subunits encoded by separate genes. FakA provides the ATP binding domain and interacts with two distinct FakB proteins to produce acyl-phosphate. The FakBs are fatty acid binding proteins that exchange bound fatty acid/acyl-phosphate with fatty acid/acyl-phosphate presented in detergent micelles or liposomes. The ΔfakA and ΔfakB1 ΔfakB2 strains were unable to incorporate extracellular fatty acids into phospholipid. FakB1 selectively bound saturated fatty acids whereas FakB2 preferred unsaturated fatty acids. Affymetrix array showed a global perturbation in the expression of virulence genes in the ΔfakA strain. The severe deficiency in α-hemolysin protein secretion in ΔfakA and ΔfakB1 ΔfakB2 mutants coupled with quantitative mRNA measurements showed that fatty acid kinase activity was ...

Products derived from the central aerobic metabolic pathway in Escherichia coli often compete with the acetate-producing pathways poxB and ackA-pta for glucose. The production of isoamyl acetate from acetyl-CoA by ATF2, a yeast alcohol acetyltransferase, was a model system to demonstrate the beneficial effects of reducing aerobic acetate production. Ester production was 80% higher in the poxB, ackA-pta strain (0.18 mM) than found in the single ackA-pta mutant, when both overexpressed the PDH complex, panK, and ATF2. Anaerobically, succinate was produced alongside isoamyl acetate to maintain the proper redox balance between NADH and NAD+. The two compounds could be easily separated in an industrial setting because of the difference in their volatilities. An ldhA, adhE double mutant strain served as the control strain to test the effect of an additional ackA-pta mutation. The triple mutant produced 36% more ester (9.4 mM) and 7 times more succinate (45.5 mM) than the control ...
Figure 1. Metabolism of pyruvate to acetate in Clostridia. The phosphoroclastic conversion of pyruvate to acetate is mediated by several iron-containing proteins. Pyruvate-ferridoxin oxidoreductase oxidizes pyruvate, using ferridoxin (Fd) as the electron acceptor. Reduced ferridoxin is then re-oxidized by a third iron-containing protein, hydrogenase. Protons serve as the electron acceptor, and hydrogen gas is formed. Phospho-transacetylase and acetate kinase catalyze the final two steps, with acetate and one mole of ATP formed as end products. Importantly, both pyruvate-ferridoxin oxidoreductase and ferridoxin are able to form complexes with nitric oxide. This would effectively block this pathway, depriving cells of ATP, as well as increasing the concentration of pyruvate to potentially toxic levels. Adapted from White, 2000.. ...

The influence of residual ethanol on metab. of food grade Gluconacetobacter xylinum I 2281 was investigated during controlled cultivations on 35 g/l glucose and 5 g/l ethanol. Bacterial growth was strongly reduced in the presence of ethanol, which is unusual for acetic acid bacteria. Biomass accumulated only after complete oxidn. of ethanol to acetate and carbon dioxide. In contrast, bacterial growth initiated without delay on 35 g/l glucose and 5 g/l acetate. It was found that acetyl CoA was activated by the acetyl CoA synthetase (Acs) pathway in parallel with the phosphotransacetylase (Pta)-acetate kinase (Ack) pathway. The presence of ethanol in the culture medium strongly reduced Pta activity while Acs and Ack remained active. A carbon balance calcn. showed that the overall catabolism could be divided into two independent parts: upper glycolysis linked to glucose catabolism and lower glycolysis linked to ethanol catabolism. This calcn. showed that the carbon flux through the tricarboxylic cycle is

Geobacillus thermoglucosidasius is a Gram-positive, thermophilic bacterium capable of ethanologenic fermentation of both C5 and C6 sugars and may have possible use for commercial bioethanol production [Tang et al., 2009; Taylor et al. (2009) Trends Biotechnol 27(7): 398-405]. Little is known about the physiological changes that accompany a switch from aerobic (high redox) to microaerobic/fermentative (low redox) conditions in thermophilic organisms. The changes in the central metabolic pathways in response to a switch in redox potential were analyzed using quantitative real-time PCR and proteomics. During low redox (fermentative) states, results indicated that glycolysis was uniformly up-regulated, the Krebs (tricarboxylic acid or TCA) cycle non-uniformly down-regulated and that there was little to no change in the pentose phosphate pathway. Acetate accumulation was accounted for by strong down-regulation of the acetate CoA ligase gene (acs) in addition to up-regulation of the pta and ackA genes ...

Syntrophus aciditrophicusis a model syntrophic bacterium that degrades key intermediates in anaerobic decomposition, such as benzoate, cyclohexane-1-carboxylate, and certain fatty acids, to acetate when grown with hydrogen-/formate-consuming microorganisms. ATP formation coupled to acetate production is the main source for energy conservation byS. aciditrophicus. However, the absence of homologs for phosphate acetyltransferase and acetate kinase in the genome ofS. aciditrophicusleaves it unclear as to how ATP is formed, as most fermentative bacteria rely on these two enzymes to synthesize ATP from acetyl coenzyme A (CoA) and phosphate. Here, we combine transcriptomic, proteomic, metabolite, and enzymatic approaches to show thatS. aciditrophicususes AMP-forming, acetyl-CoA synthetase (Acs1) for ATP synthesis from acetyl-CoA.acs1mRNA and Acs1 were abundant in transcriptomes and proteomes, respectively, ofS. aciditrophicusgrown in pure culture and coculture. Cell extracts ofS. aciditrophicushad low ...
