摘要：

The nucleotide sequence of the SHV-5 β-lactamase gene, subcloned from a plasmid of Klebsiella pneumoniae, was determined. The amino acid changes thought to be responsible for the extended substrate profile of SHV-5 are Gly → Ser234 and Glu → Lys235. SHV-5 is identical to SHV-4, except for Leu → Arg201, which accounts for the difference in apparent pI of the two enzymes.
