The protein

Protein family

• HslV subfamily (according to Swiss-Prot)

Structure

• [PDB|2Z3B]

[SW|Localization]

• cytoplasm, forms small foci, usually positioned near the cell membrane, formation of foci depends on the presence of the cognate ATPase [protein|2A5A080273CB7698DFABB147F4143E90BBCA3B01|ClpY] [Pubmed|18689473]
