Function

GVPA_DOLFA Gas vesicles (GV) are hollow, gas filled proteinaceous nanostructures found in some microorganisms. During planktonic growth they allow positioning of the organism at a favorable depth for light or nutrient acquisition. GVs are highly permeable to gas (Ref.7). GvpA forms the protein shell (PubMed:14695294, PubMed:1527496, PubMed:20858439, PubMed:22147705, PubMed:3098234, PubMed:3141741, PubMed:6409075, Ref.5). The ratio of GvpA:GvpC is estimated to be 33:1 and more recently 25:1 (PubMed:3141741, PubMed:8254305).^[1] ^[2] ^[3] ^[4] ^[5] ^[6] ^[7] ^[8] ^[9] ^[10] ^[11]
