Cloned(Commentary)
| EC Number | Cloned (Comment) | Organism |
|---|---|---|
| 3.5.2.6 | gene blaSHV-14, recombinant expression of N-terminally His6-tagged wild-type and mutant enzymes in Escherichia coli strains BL21(DE3) and CS109. On expression, the clone of wild-type SHV-14 aggravates the resistance of host by 60-500 folds against penicillin and cephalosporin groups of antibiotics, while the expression of mutated enzymes (especially E164A) substantially reduces the resistance level as compared to the wild-type, and the results are in synchrony with the estimated enzymatic efficiencies of wild-type and mutated proteins | Klebsiella pneumoniae |
Protein Variants
| EC Number | Protein Variants | Comment | Organism |

| 3.5.2.6 | malfunction | mutation at the glutamate residues in the omega-loop of SHV-14, i.e. E126, E164, and E167, can considerably modulate the beta-lactam sensitivity and reduce hydrolysis. The mutations in SHV-14 render beta-lactamase inhibitors more efficient. The mutations alter the active site configuration of SHV-14 | Klebsiella pneumoniae |
