serCPossible phosphoserine aminotransferase SerC (PSAT); Catalyzes the reversible conversion of 3- phosphohydroxypyruvate to phosphoserine and of 3-hydroxy-2-oxo-4- phosphonooxybutanoate to phosphohydroxythreonine; Belongs to the class-V pyridoxal-phosphate-dependent aminotransferase family. SerC subfamily. (376 aa)
dapCProbable N-succinyldiaminopimelate aminotransferase DapC (DAP-at); Involved in the lysine biosynthetic pathways. It catalyzes the transfer of an amino group from L-glutamate to N-succinyl-2-l- amino-6-oxoheptanedioate (N-succinyl-2-l-amino-6-ketopimelate) in a PLP-dependent reaction, yielding as products N-succinyl-l-2,6- diaminoheptanedioate (N-succinyl-diaminopimelate) and 2-oxoglutarate (Probable); Belongs to the class-III pyridoxal-phosphate-dependent aminotransferase family. (397 aa)
cysK2S-sulfocysteine synthase; Catalyzes the synthesis of S-sulfocysteine, utilizing O- phosphoserine (OPS) and thiosulfate as substrates. To a lesser extent, can also use sulfide as donor substrate, producing L-cysteine. CysK2 thus provides a third metabolic route to cysteine, either directly using sulfide as donor or indirectly via S-sulfocysteine. S- sulfocysteine might also act as a signaling molecule triggering additional responses in redox defense in the pathogen upon exposure to reactive oxygen species during intracellular survival or dormancy. Cannot utilize thiocarboxylated CysO as [...] (372 aa)
proCProbable pyrroline-5-carboxylate reductase ProC (P5CR) (P5C reductase); Catalyzes the reduction of 1-pyrroline-5-carboxylate (PCA) to L-proline. (295 aa)
metZProbable O-succinylhomoserine sulfhydrylase MetZ (OSH sulfhydrylase); Catalyzes the formation of L-homocysteine from O-succinyl-L- homoserine (OSHS) and hydrogen sulfide. (406 aa)
ilvDRv0189c, (MTCI28.28c), len: 575 aa. Probable ilvD,dihydroxy-acid dehydratase, similar to many e.g. ILVD_LACLA|Q02139 dihydroxy-acid dehydratase (dad) from Lactococcus lactis (subsp. lactis) (Streptococcus lactis) (570 aa), FASTA scores: opt: 1605, E(): 0, (46.0% identity in 561 aa overlap). Also similar to ML2608|MLCL622.06c|O06069|ILVD_MYCLE dihydroxy-acid dehydratase from Mycobacterium leprae (564 aa). Contains PS00886 Dihydroxy-acid and 6-phosphogluconate dehydratases signature 1. Belongs to the ILVD / EDD family. Cofactor: binds 1 4FE-4S cluster (potential). (575 aa)
mtn5'-methylthioadenosine/S-adenosylhomocysteine nucleosidase; Catalyzes the irreversible cleavage of the glycosidic bond in both 5'-methylthioadenosine (MTA) and S-adenosylhomocysteine (SAH/AdoHcy) to adenine and the corresponding thioribose, 5'- methylthioribose and S-ribosylhomocysteine, respectively. (255 aa)
glyA2Serine hydroxymethyltransferase GlyA2 (serine methylase 2) (SHMT 2); Catalyzes the reversible interconversion of serine and glycine with tetrahydrofolate (THF) serving as the one-carbon carrier. This reaction serves as the major source of one-carbon groups required for the biosynthesis of purines, thymidylate, methionine, and other important biomolecules. Also exhibits THF-independent aldolase activity toward beta-hydroxyamino acids, producing glycine and aldehydes, via a retro-aldol mechanism. Thus, is able to catalyze the cleavage of L- allo-threonine; Belongs to the SHMT family. (425 aa)
trpGPossible anthranilate synthase component II TrpG (glutamine amidotransferase); Part of a heterotetrameric complex that catalyzes the two- step biosynthesis of anthranilate, an intermediate in the biosynthesis of L-tryptophan. In the first step, the glutamine-binding beta subunit (TrpG) of anthranilate synthase (AS) provides the glutamine amidotransferase activity which generates ammonia as a substrate that, along with chorismate, is used in the second step, catalyzed by the large alpha subunit of AS (TrpE) to produce anthranilate. In the absence of TrpG, TrpE can synthesize anthranilat [...] (232 aa)
