Definition of trpA

• HMM TIGR00262
• Curated sequence Q9YGA9: tryptophan synthase subunit α (EC 4.1.2.8). tryptophan synthase (subunit 1/2) (EC 4.2.1.20)
• UniProt sequence A0A3N7DTH5: RecName: Full=Tryptophan synthase alpha chain {ECO:0000256|HAMAP-Rule:MF_00131}; EC=4.2.1.20 {ECO:0000256|HAMAP-Rule:MF_00131};
• UniProt sequence H0BV16: RecName: Full=Tryptophan synthase alpha chain {ECO:0000256|HAMAP-Rule:MF_00131}; EC=4.2.1.20 {ECO:0000256|HAMAP-Rule:MF_00131};
• UniProt sequence M4NLA4: RecName: Full=Tryptophan synthase alpha chain {ECO:0000256|HAMAP-Rule:MF_00131}; EC=4.2.1.20 {ECO:0000256|HAMAP-Rule:MF_00131};
• Ignore hits to items matching EC 4.2.1.20 when looking for 'other' hits
• Ignore hits to items matching EC 4.1.2.8 when looking for 'other' hits
• Comment: This reaction is 4.1.2.8 by itself or part of 4.2.1.20. The enzyme from Pyrolobus is not matched by the HMM, but is similar to the characterized trpA from Thermococcus (Q9YGA9, see PMID:11029579) APJEIK_06300 from Pedobacter sp. FW305-3-2-15-E-R2A2 (A0A3N7DTH5) can complement a trpA- strain of E. coli (Bradley Biggs). GAMENC_07330 from Acidovorax sp. FHTAMBA (H0BV16) can complement a trpA- strain of E. coli (Bradley Biggs); also it is very similar to Ac3H11_1535, which has auxotrophic phenotypes. LRK54_RS01680 from Rhodanobacter sp. FW104-10B01 (M4NLA4) can complement a trpA- strain of E. coli (Bradley Biggs); also it is similar to N515DRAFT_0116, which has auxotrophic pheonotypes.
