Gene

hlyB

Organism
Escherichia coli
Status
Reviewed-Annotation score: Annotation score: 4 out of 5-Experimental evidence at protein leveli

Miscellaneousi

Miscellaneous

The complex HlyBD-TolC (OMF) forms a single transport channel across the two membranes, allowing direct export of alpha-hemolysin. This channel is involved in type 1 secretion system.

Caution

Tyr-9 is present instead of the conserved Cys which is expected to be the active site residue of peptidase C39. Thus this protein is presumed to be without peptidase activity.Curated

Similar proteinsi

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
