Alkalophilic Bacillus sp. strain LG12 has a series of serine protease genes

Abstract

Four tandem subtilisin-like protease genes were found on a 6,854-bp DNA fragment cloned from the alkalophilic Bacillus sp. strain LG12. The two downstream genes (sprC and sprD) appear to be transcribed independently, while the two upstream genes (sprA and sprB) seem to be part of the same transcript.
