Retracted: Cloning, expression, crystallization and preliminary X-ray crystallographic analysis of aspartyl aminopeptidase from the apeB gene of Pseudomonas aeruginosa

Aspartyl aminopeptidase (APP) is a metallopeptidase that catalyzes the hydrolysis of aspartic acid from the N-termini of polypeptide chains. The apeB gene from P. aeruginosa was cloned, the APP enzyme was expressed and crystallized and a preliminary X-ray crystallographic study was performed in order to understand its unique reaction pathway.
