GvpA is a gas vesicle structural protein found in different phyla of bacteria and archea for example in Halobacterium salinarum or Haloferax mediterranei. It associates with GvpC, to build up gas vesicles, hollow protein structures which are used by planktonic organisms to perform vertical migration. GvpA makes up most of the structure, whereas GvpC stabilizes the vesicle against collapse. [1] [2] [3]
Structure
GvpA of Halobacterium salinarum is a 76 amino acid long 8kDa monomer.[2]
