The Aeromonas veronii bv. sobria metallo-
-lactamase
gene, imiS, was cloned. The imiS open reading
frame extends for 762 bp and encodes a protein of 254 amino acids with
a secreted modified protein of 227 amino acids and a predicted pI of
8.1. To confirm the predicted sequence, purified ImiS was digested and
the resulting peptides were identified, yielding an identical sequence
for ImiS, with 98% identity to CphA. Both possessed the putative
active-site sequence Asn-Tyr-His-Thr-Asp at positions 88 to 92, which
is unique to the Aeromonas metallo-
-lactamases.
