Protein

ATP-dependent zinc metalloprotease FtsH

Gene

ftsH

Organism
Bacillus subtilis (strain 168)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

Acts as a processive, ATP-dependent zinc metallopeptidase for both cytoplasmic and membrane proteins. Plays a role in the quality control of integral membrane proteins.UniRule annotation
In vitro partially degrades Spo0E, the phosphatase that acts on Spo0A-P. Recognition requires the last 14 residues of Spo0E.

  • Cell membrane 1 Publication; Multi-pass membrane protein 1 Publication; Cytoplasmic side 1 Publication

  • Note: Accumulates in the midcell septum during vegetative cell division. At the onset of sporulation appears at positions near the cell poles that may coincide with future division sites. Then, FtsH becomes concentrated at the sporulation septum and disappears from the distal pole.

Pathology & Biotechi

Disruption phenotypei

Required for expression of the stage 0 sporulation gene Spo0A, as well as for a normal heat or osmotic stress response, cells lacking this gene grow as long filaments and tend to lyse upon entry into stationary phase. Secretion of some extracellular proteins is also reduced.1 Publication

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.
