[[https://www.uniprot.org/uniprot/PURL_THEMA PURL_THEMA]] 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.

== Publication Abstract from PubMed ==
Formylglycinamide ribonucleotide amidotransferase (FGAR-AT) catalyzes the ATP-dependent synthesis of formylglycinamidine ribonucleotide (FGAM) from formylglycinamide ribonucleotide (FGAR) and glutamine in the fourth step of the purine biosynthetic pathway. FGAR-AT is encoded by the purL gene. Two types of PurL have been detected. The first type, found in eukaryotes and Gram-negative bacteria, consists of a single 140 kDa polypeptide chain and is designated large PurL (lgPurL). The second type, small PurL (smPurL), is found in archaea and Gram-positive bacteria and consists of an 80 kDa polypeptide chain. SmPurL requires two additional gene products, PurQ and PurS, for activity. PurL is a member of a protein superfamily that contains a novel ATP-binding domain. Structures of several members of this superfamily are available in the unliganded form. We determined five different structures of FGAR-AT from Thermotoga maritima in the presence of substrates, a substrate analogue, and a product. These complexes have allowed a detailed description of the novel ATP-binding motif. The availability of a ternary complex enabled mapping of the active site, thus identifying potential residues involved in catalysis. The complexes show a conformational change in the active site compared to the unliganded structure. Surprising discoveries, an ATP molecule in an auxiliary site of the protein and the conformational changes associated with its binding, provoke speculation about the regulatory role of the auxiliary site in formation of the PurLSQ complex as well as the evolutionary relationship of PurLs from different organisms.
