G51S/S52T double mutant of L. casei FPGSG51S/S52T double mutant of L. casei FPGS

Structural highlights

2gcb is a 1 chain structure with sequence from Lacticaseibacillus casei. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.
Method:X-ray diffraction, Resolution 2.3Å
Resources:FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT

Function

FPGS_LACCA Involved in the conversion of folates to polyglutamate derivatives, and likely functions in the retention of cellular folate pools. Catalyzes successive MgATP-dependent additions of glutamate to a pteroylmonoglutamate substrate, with a high preference for 5,10-methylenetetrahydrofolate (mTHF). Thus, metabolizes mTHF to the tetraglutamate derivative, but longer glutamate chain length products are not observed. Tetrahydrofolate (H4PteGlu) and 10-formyl-H4PteGlu are poorer folate substrates. In contrast to E.coli FolC, this enzyme does not display dihydrofolate synthase activity.[1] [2]
