simple intramolecular cyclization. The mechanism consists of the following main steps: 1. intramolecular nucleophilic attack on the gamma-C=O carbon by the nitrogen of the alpha-amino group, 2. transfer of a proton from the alpha-amino group to the nitrogen of the amide group, facilitated by an acidic group of the enzyme, 3. expulsion of the ammonia-leaving group promoted by this or another acidic enzyme group

highest specificities are observed with substrates possessing large hydrophobic residues adjacent to the N-terminal glutamine and for fluorogenic dipeptide surrogates. Enzyme also catalyzes the conversion of N-terminal glutamic acid residues to pyroglutamic acid, but with about 100000fold lower specificity

substrate specificity for substrates with uncharged backbone does not change significantly by salt addition. For substrates such as Gln-Ala and Gln-Glu, addition of KCl decreases specificity. With the positively charged substrates Gln-Arg-Gly-Ile-NH2 and Gln-Lys-Arg-Leu-NH2 addition of salt reveals a positive effect on catalysis

expression in Pichia pastoris
-
expression in Escherichia coli as either His-tagged enzyme with three different signal peptides and in fusions with three different signal peptides and in fusion with thioredoxin, glutathione S-transferase, and (pre-)maltose-binding protein. In all cases, the expressed protein is either undetectable or insoluble. Expression in Pichia pastoris of the enzyme fused to the alpha-factor leader results in low levels of activity. Extracellular expression of the enzyme in the insect cell/baculovirus system is sucessfull. Enzyme N-terminally fused to a combined secretion signal/His-tag peptide is correctly processed by the host signal peptidase and the His-tag can subsequently be removed with dipeptidyl peptidase I
