'''PRECURSOR MUTANT CYS1SER OF PENICILLIN V ACYLASE FROM BACILLUS SPHAERICUS'''<br />

==Overview==
+
==precursor mutant Cys1Ser of Penicillin V Acylase from Bacillus sphaericus==
-
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.

== Function ==
 +
[https://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.
