Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance. Method: X-ray diffraction, Resolution 2Å Ligands: BMA, EDO, NAG, SO4, ZN Resources: FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT Function QPCT1_DROME Acts as a glutaminyl-peptide cyclotransferase (PubMed:17722885, PubMed:22897232). Responsible for the biosynthesis of pyroglutamyl peptides (By similarity). Might be more efficient in the conversion of tri and tetrapeptides in vitro (PubMed:17722885). Might have a relative preference for substrates containing hydrophobic amino acids in vitro (PubMed:17722885).[UniProtKB:Q16769] Publication Abstract from PubMed The structure of ligand-free glutaminyl cyclase (QC) from Drosophila melanogaster (DmQC) has been determined in a novel crystal form. The protein crystallized in space group I4, with unit-cell parameters a = b = 122.3, c = 72.7 A. The crystal diffracted to a resolution of 2 A at the home source. The structure was solved by molecular replacement and was refined to an R factor of 0.169. DmQC exhibits a typical alpha/beta-hydrolase fold. The electron density of three monosaccharides could be localized. The accessibility of the active site will facilitate structural studies of novel inhibitor-binding modes.
