Phosphoribosylformylglycinamidine synthase subunit PurL

Gene

purL

Organism
Ignisphaera aggregans (strain DSM 17230 / JCM 13409 / AQ1.S1)
Status
Unreviewed-Annotation score: Annotation score: 3 out of 5-Protein inferred from homologyi

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.UniRule annotation

Catalytic activityi

ATP + N2-formyl-N1-(5-phospho-D-ribosyl)glycinamide + L-glutamine + H2O = ADP + phosphate + 2-(formamido)-N1-(5-phospho-D-ribosyl)acetamidine + L-glutamate.UniRule annotation

Pathwayi: IMP biosynthesis via de novo pathway

This protein is involved in step 1 of the subpathway that synthesizes 5-amino-1-(5-phospho-D-ribosyl)imidazole from N(2)-formyl-N(1)-(5-phospho-D-ribosyl)glycinamide.UniRule annotation
Proteins known to be involved in the 2 steps of the subpathway in this organism are:
  1. Phosphoribosylformylglycinamidine synthase subunit PurQ (purQ), Phosphoribosylformylglycinamidine synthase subunit PurS (purS), Phosphoribosylformylglycinamidine synthase subunit PurL (purL)
  2. no protein annotated in this organism
This subpathway is part of the pathway IMP biosynthesis via de novo pathway, which is itself part of Purine metabolism.
