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.

Structural highlights

2iwm is a 4 chain structure with sequence from Lysinibacillus sphaericus. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.
Method:X-ray diffraction, Resolution 2.5Å
Resources:FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT

Function

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.

Evolutionary Conservation

Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf.
