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 (By
CC       similarity). It is not clear if the 2 type A proteins in this organism
CC       are functionally redundant (PubMed:9573198). {ECO:0000255|HAMAP-
CC       Rule:MF_00576, ECO:0000269|PubMed:9573198}.
CC   -!- SUBCELLULAR LOCATION: Vacuole, gas vesicle membrane {ECO:0000255|HAMAP-
CC       Rule:MF_00576, ECO:0000305|PubMed:9573198}. Note=When the gvp locus is
CC       expressed in E.coli gas vesicles are made.
CC       {ECO:0000269|PubMed:9573198}.
CC   -!- DISRUPTION PHENOTYPE: Not essential for gas vesicle formation in
CC       E.coli. {ECO:0000269|PubMed:9573198}.
CC   -!- SIMILARITY: Belongs to the gas vesicle protein type A family.
CC       {ECO:0000255|HAMAP-Rule:MF_00576}.
