CRYSTAL STRUCTURE OF A BINARY COMPLEX OF E. COLI DIHYDROPTEROATE SYNTHASECRYSTAL STRUCTURE OF A BINARY COMPLEX OF E. COLI DIHYDROPTEROATE SYNTHASE

Structural highlights

1aj2 is a 1 chain structure with sequence from Escherichia coli. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.
Method:X-ray diffraction, Resolution 2Å
Ligands:,
Resources:FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT

Function

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

Evolutionary Conservation

Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf.
