Gene
purL, BMEI1127
Organism
Brucella melitensis biotype 1 (strain 16M / ATCC 23456 / NCTC 10094)
Status

Functioni

Part of the phosphoribosylformylglycinamidine synthase complex involved in the purines biosynthetic pathway. Catalyzes the ATP-dependent conversion of formylglycinamide ribonucleotide (FGAR) and glutamine to yield formylglycinamidine ribonucleotide (FGAM) and glutamate. The FGAM synthase complex is composed of three subunits. PurQ produces an ammonia molecule by converting glutamine to glutamate. PurL transfers the ammonia molecule to FGAR to form FGAM in an ATP-dependent manner. PurS interacts with PurQ and PurL and is thought to assist in the transfer of the ammonia molecule from PurQ to PurL By similarity.

Catalytic activityi

ATP + N(2)-formyl-N(1)-(5-phospho-D-ribosyl)glycinamide + L-glutamine + H2O = ADP + phosphate + 2-(formamido)-N(1)-(5-phospho-D-ribosyl)acetamidine + L-glutamate.UniRule annotation

Miscellaneousi

Miscellaneous

In Gram-negative bacteria and most eukaryotes, FGAM synthase is only formed by PurL, a single polypeptide of 140 kDa (large PurL). However in Gram-positive bacteria and archaebacteria, phosphoribosylformylglycinamidine synthase is composed of three separate proteins: PurL (small PurL), PurQ and PurS By similarity.
