Abstract
The M(w) of a Lactobacillus sakei intracellular esterase, determined by gel filtration, was compared to those obtained from SDS-PAGE or MALDI-TOF, pointing to a dimeric structure. Its N-terminal sequence and peptide mass fingerprint suggest that it is the putative LSA044 protein from L. sakei 23K genome.
