Journal ArticleDOI

Complete genome sequence of Lactobacillus plantarum WCFS1

TL;DR: The 3,308,274-bp sequence of the chromosome of Lactobacillus plantarum strain WCFS1, a single colony isolate of strain NCIMB8826 that was originally isolated from human saliva, has been determined, and contains 3,052 predicted protein-encoding genes, suggesting that these genes form a lifestyle adaptation region in the chromosome.
Journal ArticleDOI

Subtilases: the superfamily of subtilisin-like serine proteases.

TL;DR: Details of more than 100 new subtilases discovered in the past five years are summarized, and amino acid sequences of their catalytic domains are compared in a multiple sequence alignment.
Journal ArticleDOI

Characterization of the nisin gene cluster nisABTCIPR of Lactococcus lactis. Requirement of expression of the nisA and nisI genes for development of immunity

TL;DR: Transcription analyses of several L. lactis strains indicated that an expression product of the nisA gene, together with NisR, is required for the activation of nisinA transcription, indicating that NisI plays a role in the immunity mechanism.
Journal ArticleDOI

Identification and characterization of the lantibiotic nisin Z, a natural nisin variant

TL;DR: NMR studies of the natural nisin variant, which has been designated nisin Z, confirmed the His27Asn substitution and indicated that it has a similar structure to nisin.
Journal ArticleDOI

Epochal Evolution of GGII.4 Norovirus Capsid Proteins from 1995 to 2006

TL;DR: The consistent association between the observed genetic findings and changes in epidemiology leads to the conclusion that population immunity plays a role in the epochal evolution of GGII.4 norovirus strains.
