CC -!- FUNCTION: Might be involved in nucleating gas vesicle formation (By
CC similarity). Gas vesicles (GV) are hollow, gas filled proteinaceous
CC nanostructures. During planktonic growth they allow positioning of the
CC organism at a favorable depth for light or nutrient acquisition.
CC {ECO:0000250|UniProtKB:P24375}.
CC -!- FUNCTION: Cluster expression in E.coli (gvpA1-gvpA2-gvpC-gvpN-gvpJ-
CC gvpK-gvpF-gvpG-gvpV-gvpW) allows cells to float and produces
CC irregularly shaped gas vesicles. {ECO:0000269|PubMed:32375647}.
CC -!- SUBCELLULAR LOCATION: Gas vesicle {ECO:0000305}.
CC -!- SIMILARITY: Belongs to the gas vesicle GvpK family. {ECO:0000305}.
CC -!- CAUTION: Despite the presence of an intact gas vesicle cluster and gvpA
CC transcripts, there is no evidence this strain produces gas vesicles.
CC {ECO:0000269|PubMed:32375647}.
