Function

function

Gas vesicles 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. GvpA forms the protein shell.
Cluster expression in E.coli (gvpA1-gvpA2-gvpC-gvpN-gvpJ-gvpK-gvpF-gvpG-gvpV-gvpW) allows cells to float and produces irregularly shaped gas vesicles.

Caution

Despite the presence of an intact gas vesicle cluster and gvpA transcripts, there is no evidence this strain produces gas vesicles.

ChainPRO_00001999792-71Gas vesicle protein A

Expression

Induction

Constitutively transcribed when grown in a 12 hour light/dark regime at 2000 umol photon/m2/s; decreased light, growth at 38 degrees Celsius or both increased transcripts up to 23-fold.

Interaction

Subunit

The gas vesicle shell is 2 nm thick and consists of a single layer of this protein. It forms helical ribs nearly perpendicular to the long axis of the vesicle.
