Organism
Streptococcus pyogenes serotype M3 (strain ATCC BAA-595 / MGAS315)
Status
Reviewed-Annotation score: Annotation score: 3 out of 5-Protein inferred from homologyi

Functioni

Catalyzes the condensation of para-aminobenzoate (pABA) with 6-hydroxymethyl-7,8-dihydropterin diphosphate (DHPt-PP) to form 7,8-dihydropteroate (H2Pte), the immediate precursor of folate derivatives.By similarity

Catalytic activityi

6-hydroxymethyl-7,8-dihydropterin diphosphate + 4-aminobenzoate = diphosphate + dihydropteroate.By similarity

Cofactori

Mg2+By similarity

Pathwayi: tetrahydrofolate biosynthesis

This protein is involved in step 1 of the subpathway that synthesizes 7,8-dihydrofolate from 2-amino-4-hydroxy-6-hydroxymethyl-7,8-dihydropteridine diphosphate and 4-aminobenzoate.
Proteins known to be involved in the 2 steps of the subpathway in this organism are:
  1. Dihydropteroate synthase (folP)
  2. no protein annotated in this organism
This subpathway is part of the pathway tetrahydrofolate biosynthesis, which is itself part of Cofactor biosynthesis.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes 7,8-dihydrofolate from 2-amino-4-hydroxy-6-hydroxymethyl-7,8-dihydropteridine diphosphate and 4-aminobenzoate, the pathway tetrahydrofolate biosynthesis and in Cofactor biosynthesis.

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
