Lantibiotic dehydratase, N terminus; Lantibiotics are ribosomally synthesized antimicrobial agents derived from ribosomally synthesized peptides. They are produced by bacteria of the Firmicutes phylum, and include mutacin, subtilin, and nisin. Lantibiotic peptides contain thioether bridges termed lanthionines that are thought to be generated by dehydration of serine and threonine residues followed by addition of cysteine residues. This family constitutes the N-terminus of the enzyme proposed to catalyze the dehydration step via glutamylation of the substrate during lantibiotic biosynthesis. The enzyme dehydrates Ser/Thr residues in the precursor by glutamylation.

thiopeptide-type bacteriocin biosynthesis domain; This domain occurs within longer proteins that contain lantibiotic dehydratase domains (see pfam04737 and pfam04738), and as single-domain proteins in bacteriocin biosynthesis genomic contexts. Three named genes in this family, SioK in Streptomyces sioyaensis, TsrD in Streptomyces laurentii, and NosD in Streptomyces actuosus, all occur in regions associated with thiopeptide biosynthesis.

Lantibiotic biosynthesis dehydratase C-term; Lant_dehydr_C is the C-terminal domain of a family of dehydratases that are involved in the biosynthesis of lantibiotics. While the extensive N-terminal domain, pfam04738, is involved in the serine-threonine glutamylation step of the synthetic process, this C-terminal domain, once thought to be a separate domain from the dehydratase enzymic activity, is necessary for the final glutamate-elimination step in the generation of the lantibiotic. Lantibiotics are a class of peptide antibiotic that contains one or more thioether bonds.

Domains are color coded according to superfamilies
to which they have been assigned. Hits with scores that pass a domain-specific threshold
(specific hits) are drawn in bright colors.
Others (non-specific hits) and
superfamily placeholders are drawn in pastel colors.
if a domain or superfamily has been annotated with functional sites (conserved features),
they are mapped to the query sequence and indicated through sets of triangles
with the same color and shade of the domain or superfamily that provides the annotation. Mouse over the colored bars or triangles to see descriptions of the domains and features.

(labeled illustration) Four types of hits can be shown, as available,
for each region on the query sequence:
specific hits meet or exceed a domain-specific e-value threshold
(illustrated example)
and represent a very high confidence that the query sequence belongs to the same protein family as the sequences use to create the domain model
non-specific hits
