Organism

Prochlorococcus marinus (strain MIT 9313) [Complete proteome] [HAMAP]

Taxonomic identifier

74547 [NCBI]

Taxonomic lineage

Bacteria › Cyanobacteria › Prochlorophytes › Prochlorococcaceae › Prochlorococcus

Protein attributes

Sequence length	197 AA.
Sequence status	Complete.
Protein existence	Inferred from homology

General annotation (Comments)

Function	Cleaves peptides in various proteins in a process that requires ATP hydrolysis. Has a chymotrypsin-like activity. Plays a major role in the degradation of misfolded proteins By similarity. HAMAP MF_00444
Catalytic activity	Hydrolysis of proteins to small peptides in the presence of ATP and magnesium. Alpha-casein is the usual test substrate. In the absence of ATP, only oligopeptides shorter than five residues are hydrolyzed (such as succinyl-Leu-Tyr-|-NHMec; and Leu-Tyr-Leu-|-Tyr-Trp, in which cleavage of the -Tyr-|-Leu- and -Tyr-|-Trp bonds also occurs). HAMAP MF_00444
Subcellular location	Cytoplasm By similarity HAMAP MF_00444.
Sequence similarities	Belongs to the peptidase S14 family.
