== Function == | |||
[https://www.uniprot.org/uniprot/QPCT1_DROME 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]<ref>PMID:17722885</ref> <ref>PMID:22897232</ref> | |||

== 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. | |||
