OX NCBI_TaxID=107806; RN [1] RP NUCLEOTIDE SEQUENCE [LARGE SCALE GENOMIC DNA]. RC STRAIN=APS; RX PubMed=10993077; DOI=10.1038/35024074; RA Shigenobu S., Watanabe H., Hattori M., Sakaki Y., Ishikawa H.; RT "Genome sequence of the endocellular bacterial symbiont of aphids RT Buchnera sp. APS."; RL Nature 407:81-86(2000). CC -!- FUNCTION: Functions in two distinct reactions of the de novo CC folate biosynthetic pathway. Catalyzes the addition of a glutamate CC residue to dihydropteroate (7,8-dihydropteroate or H2Pte) to form CC dihydrofolate (7,8-dihydrofolate monoglutamate or H2Pte-Glu). Also CC catalyzes successive additions of L-glutamate to tetrahydrofolate CC or 10-formyltetrahydrofolate or 5,10-methylenetetrahydrofolate, CC leading to folylpolyglutamate derivatives. CC {ECO:0000250|UniProtKB:P08192}. CC -!- CATALYTIC ACTIVITY: ATP + 7,8-dihydropteroate + L-glutamate = ADP CC + phosphate + 7,8-dihydropteroylglutamate. CC {ECO:0000250|UniProtKB:P08192}. CC -!- CATALYTIC ACTIVITY: ATP + tetrahydropteroyl-(gamma-Glu)(n) + L- CC glutamate = ADP + phosphate + tetrahydropteroyl-(gamma-Glu)(n+1). CC {ECO:0000250|UniProtKB:P08192}. CC -!- CATALYTIC ACTIVITY: ATP + 10-formyl-tetrahydropteroyl-(gamma- CC Glu)(n) + L-glutamate = ADP + phosphate + 10-formyl- CC tetrahydropteroyl-(gamma-Glu)(n+1). CC {ECO:0000250|UniProtKB:P08192}. CC -!- CATALYTIC ACTIVITY: ATP + 5,10-methylene-tetrahydropteroyl-(gamma- CC Glu)(n) + L-glutamate = ADP + phosphate + 5,10-methylene- CC tetrahydropteroyl-(gamma-Glu)(n+1). CC {ECO:0000250|UniProtKB:P08192}. CC -!- COFACTOR: CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420; CC Evidence={ECO:0000250|UniProtKB:P08192}; CC Note=Binds 2 Mg(2+) ions per subunit. CC {ECO:0000250|UniProtKB:P08192}; CC -!- PATHWAY: Cofactor biosynthesis; tetrahydrofolate biosynthesis; CC 7,8-dihydrofolate from 2-amino-4-hydroxy-6-hydroxymethyl-7,8- CC dihydropteridine diphosphate and 4-aminobenzoate: step 2/2. CC {ECO:0000250|UniProtKB:P08192}. CC -!- PATHWAY: Cofactor biosynthesis; tetrahydrofolylpolyglutamate CC biosynthesis. {ECO:0000250|UniProtKB:P08192}. CC -!- SUBUNIT: Monomer. {ECO:0000250|UniProtKB:P08192}. CC -!- SIMILARITY: Belongs to the folylpolyglutamate synthase family. CC {ECO:0000305}.
