Abstract

Lactobacillus brevis possesses a surface layer protein (SlpA) with tightly regulated synthesis. The slpA gene is expressed by two adjacent promoters, P1 and P2. The level of P2-derived transcripts was approximately 10 times higher than that of P1-derived transcripts throughout the entire growth of L. brevis. The half-lives of slpA transcripts were shown to be exceptionally long (14 min).
