Functioni

DHPS catalyzes the formation of the immediate precursor of folic acid. It is implicated in resistance to sulfonamide.1 Publication

Catalytic activityi

6-hydroxymethyl-7,8-dihydropterin diphosphate + 4-aminobenzoate = diphosphate + dihydropteroate.1 Publication

Cofactori

Mg2+Note: Binds 1 Mg2+ ion per subunit. Magnesium is required for activity, even if it interacts primarily with the substrate.

Pathway: 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), Dihydropteroate synthase (folP), Dihydropteroate synthase (folP), Dihydropteroate synthase (folP), Dihydropteroate synthase (folP), Dihydropteroate synthase (folP), Dihydropteroate synthase (folP), Dihydropteroate synthase (folP), Dihydropteroate synthase (folP), 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 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.
