Nucleotide sequences of genes encoding the type II chloramphenicol acetyltransferases of Escherichia coli and Haemophilus influenzae, which are sensitive to inhibition by thiol-reactive reagents.

Abstract excerpt

Sensitivity of enzymes to inhibition by thiol-reactive reagents is often presented as evidence for the possible involvement of cysteine residues in substrate binding and catalysis or to highlight possible important differences in structure and mechanism between closely related enzymes. The primary phenotypic distinction between the enterobacterial type II chloramphenicol acetyltransferase (CATII; typified by the...
