[[http://www.uniprot.org/uniprot/PAC_LYSSH PAC_LYSSH]] The enzyme catalyzes the conversion of penicillin to 6-aminopenicillanate The precursor, furthermore, acts as a self-processing peptidase that cleaves off the propeptide. All peptidase activity is lost on conversion to the mature peptidase.

== Publication Abstract from PubMed ==

The crystallization of three catalytically inactive mutants of penicillin V acylase (PVA) from Bacillus sphaericus in precursor and processed forms is reported. The mutant proteins crystallize in different primitive monoclinic space groups that are distinct from the crystal forms for the native enzyme. Directed mutants and clone constructs were designed to study the post-translational autoproteolytic processing of PVA. The catalytically inactive mutants will provide three-dimensional structures of precursor PVA forms, plus open a route to the study of enzyme-substrate complexes for this industrially important enzyme.
