title: Cloning, nucleotide sequence and expression of a beta-lactamase gene from Streptomyces lavendulae.
abstract: A hybridized DNA fragment was cloned as a 7.6-kb fragment from Streptomyces lavendulae KCCS0263 using a 1.9-kb SacI-XbaI DNA fragment from S. cellulosae as a probe. The latter fragment encoded a beta-lactamase which can bind blue dextran. The hybridized region was reduced to a 2.8-kb KpnI-BclI fragment and the nucleotide sequence was determined. The nucleotide sequence indicated one open reading frame whose amino acid sequence is very similar to that of the beta-lactamase from S. cellulosae. The gene produced beta-lactamase enzyme at a low but significant amount.
