Identification of Escherichia coli K12 YdcW protein as a gamma-aminobutyraldehyde dehydrogenase.
Samsonova N.N., Smirnov S.V., Novikova A.E., Ptitsyn L.R.
Gamma-aminobutyraldehyde dehydrogenase (ABALDH) from wild-type E. coli K12 was purified to apparent homogeneity and identified as YdcW by MS-analysis. YdcW exists as a tetramer of 202+/-29 kDa in the native state, a molecular mass of one subunit was determined as 51+/-3 kDa. Km parameters of YdcW ... >> More
Gamma-aminobutyraldehyde dehydrogenase (ABALDH) from wild-type E. coli K12 was purified to apparent homogeneity and identified as YdcW by MS-analysis. YdcW exists as a tetramer of 202+/-29 kDa in the native state, a molecular mass of one subunit was determined as 51+/-3 kDa. Km parameters of YdcW for gamma-aminobutyraldehyde, NAD+ and NADP+ were 41+/-7, 54+/-10 and 484+/-72 microM, respectively. YdcW is the unique ABALDH in E. coli K12. A coupling action of E. coli YgjG putrescine transaminase and YdcW dehydrogenase in vitro resulted in conversion of putrescine into gamma-aminobutyric acid. << Less

Escherichia coli mutants able to grow in putrescine have been isolated from gamma-aminobutyrate mutants. These mutants show putrescine-alpha-ketoglutarate transaminase and gamma-aminobutyraldehyde dehydrogenase activities.

Escherichia coli mutants able to grow in putrescine have been isolated from gamma-aminobutyrate mutants. These mutants show putrescine-alpha-ketoglutarate transaminase and gamma-aminobutyraldehyde dehydrogenase activities. Both enzymes have been characterized, the first of them showing an apparent Km for putrescine of 22.5 microM and the second an apparent Km of 37 microM for NAD and 18 microM for delta-1-pyrroline; the optimum pH values were 7.2 and 5.4, respectively, for the two enzymes. << Less

<h4>Background</h4>Putrescine is the intermediate product of arginine decarboxylase pathway in Escherichia coli which can be used as an alternative nitrogen source. Transaminase and dehydrogenase enzymes seem to be implicated in the degradative pathway of putrescine, in which this compound is converted into gamma-aminobutyrate. But genes coding for these enzymes have not been identified so far.<h4>Results</h4>The 1.8-kbp DNA fragment containing E. coli K12 ygjG gene with aer-ygjG intergenic region was examined. It was found that the fragment contains sigma54-depended open reading frame (ORF) of 1,380 nucleotides encoding a 459-amino acid polypeptide of approximately 49.6 kDa. The cytidine (C) residue localized 10 bp downstream of the sigma54 promoter sequence was identified as the first mRNA base. The UUG translation initiation codon is situated 36 nucleotides downstream of the mRNA start. The YgjG was expressed as a his6-tag fused protein and purified to homogeneity. The protein catalyzed putrescine:2-oxoglutaric acid (2-OG) aminotransferase reaction (PATase, EC 2.6.1.29). The Km values for putrescine and 2-OG were found to be 9.2 mM and 19.0 mM, respectively. The recombinant enzyme also was able to transaminate cadaverine and, in lower extent, spermidine, and gave maximum activity at pH 9.0.<h4>Conclusion</h4>Expression of E. coli K12 ygjG coding region revealed sigma54-depended ORF which encodes a 459-amino acid protein with putrescine:2-OG aminotransferase activity. The enzyme also was able to transaminate cadaverine and, in lower extent, spermidine. << Less
