CC   -!- FUNCTION: SHV enzymes hydrolyze broad spectrum cephalosporins notably
CC       cefotaxime and ceftazidime. SHV-5 causes particularly high levels of
CC       resistance to aztreonam and ceftazidime.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=a beta-lactam + H2O = a substituted beta-amino acid;
CC         Xref=Rhea:RHEA:20401, ChEBI:CHEBI:15377, ChEBI:CHEBI:35627,
CC         ChEBI:CHEBI:140347; EC=3.5.2.6; Evidence={ECO:0000255|PROSITE-
CC         ProRule:PRU10101};
CC   -!- SIMILARITY: Belongs to the class-A beta-lactamase family.
CC       {ECO:0000305}.
