CC   -!- FUNCTION: Gas vesicles are small, hollow, gas filled protein structures
CC       that are found in several microbial planktonic microorganisms. They
CC       allow the positioning of the organism at the favorable depth for
CC       growth. GvpA type proteins form the essential core of the structure.
CC   -!- SUBCELLULAR LOCATION: Vacuole, gas vesicle membrane.
CC   -!- SIMILARITY: Belongs to the gas vesicle protein type A family.
CC       {ECO:0000305}.
