DE RecName: Full=Phosphoserine aminotransferase; DE EC=2.6.1.52; DE AltName: Full=Phosphohydroxythreonine aminotransferase; DE Short=PSAT; GN Name=serC; OrderedLocusNames=MS1573; OS Mannheimia succiniciproducens (strain MBEL55E). OC Bacteria; Proteobacteria; Gammaproteobacteria; Pasteurellales; OC Pasteurellaceae; Basfia. OX NCBI_TaxID=221988; RN [1] RP NUCLEOTIDE SEQUENCE [LARGE SCALE GENOMIC DNA]. RX PubMed=15378067; DOI=10.1038/nbt1010; RA Hong S.H., Kim J.S., Lee S.Y., In Y.H., Choi S.S., Rih J.-K., RA Kim C.H., Jeong H., Hur C.G., Kim J.J.; RT "The genome sequence of the capnophilic rumen bacterium Mannheimia RT succiniciproducens."; RL Nat. Biotechnol. 22:1275-1281(2004). CC -!- FUNCTION: Catalyzes the reversible conversion of 3- CC phosphohydroxypyruvate to phosphoserine and of 3-hydroxy-2-oxo-4- CC phosphonooxybutanoate to phosphohydroxythreonine (By similarity). CC -!- CATALYTIC ACTIVITY: O-phospho-L-serine + 2-oxoglutarate = 3- CC phosphonooxypyruvate + L-glutamate. CC -!- CATALYTIC ACTIVITY: 4-phosphonooxy-L-threonine + 2-oxoglutarate = CC (3R)-3-hydroxy-2-oxo-4-phosphonooxybutanoate + L-glutamate. CC -!- COFACTOR: Binds 1 pyridoxal phosphate per subunit (By similarity). CC -!- PATHWAY: Amino-acid biosynthesis; L-serine biosynthesis; L-serine CC from 3-phospho-D-glycerate: step 2/3. CC -!- PATHWAY: Cofactor biosynthesis; pyridoxine 5'-phosphate CC biosynthesis; pyridoxine 5'-phosphate from D-erythrose 4- CC phosphate: step 3/5. CC -!- SUBUNIT: Homodimer (By similarity). CC -!- SUBCELLULAR LOCATION: Cytoplasm (By similarity). CC -!- SIMILARITY: Belongs to the class-V pyridoxal-phosphate-dependent CC aminotransferase family. SerC subfamily.
