Definition of serA

• Curated proteins or TIGRFams with EC 1.1.1.95
• UniProt sequence A0A1X9ZCD3: SubName: Full=3-phosphoglycerate dehydrogenase {ECO:0000313|EMBL:ARS42937.1};
• UniProt sequence Q6LWW6: RecName: Full=D-3-phosphoglycerate dehydrogenase {ECO:0000256|RuleBase:RU363003}; EC=1.1.1.95 {ECO:0000256|RuleBase:RU363003};
• Ignore hits to Q4JDI4 when looking for 'other' hits (phosphoglycerate kinase (EC 2.7.2.3))
• Ignore hits to HP_RS05420-MONOMER when looking for 'other' hits (cinnamyl-alcohol dehydrogenase (EC 1.1.1.2; EC 1.1.1.95; EC 1.1.1.195))
• Ignore hits to SGL_RS08600-MONOMER when looking for 'other' hits (glycerate dehydrogenase (EC 1.1.1.29))
• Predicted: UniProt sequence A0A374I5P9: RecName: Full=D-3-phosphoglycerate dehydrogenase {ECO:0000256|ARBA:ARBA00021582}; EC=1.1.1.399 {ECO:0000256|ARBA:ARBA00013001}; EC=1.1.1.95 {ECO:0000256|ARBA:ARBA00013143}; AltName: Full=2-oxoglutarate reductase {ECO:0000256|ARBA:ARBA00030455};
• Comment: BRENDA::Q4JDI4 is misannotated as 3-phosphoglycerate dehydrogenase instead of 3-phosphoglycerate kinase. (The curators were notified and report that they have corrected this.) CA265_RS09010 (A0A1X9ZCD3) from Pedobacter sp. GW460-11-11-14-LB5 is annotated as 3-phosphoglycerate dehydrogenase and has auxotrophic phenotypes. In particular, mutants are partially rescued by glycine or serine. Also it is adjacent to the putative serC. MMP1588 (Q6LWW6) was identified as the serA of Methanococcus (PMC1797378). Ignore link_RS05420-MONOMER which has this EC but has a different function. Ignore similarity to sll1908 (link_RS08600-MONOMER) which seems likely to be serA but was proposed (without experimental evidence) to be hydroxpyruvate reductase. In Roseburia faecis, the putative serA (A0A374I5P9) is diverged but is similar to the serA part of Echvi_2777 and is conserved next to serC and DUF1015 (putative serB).
