pfam07088: GvpD_P-loop 
GvpD gas vesicle protein, P-loop domain
This family consists of several archaeal GvpD gas vesicle regulatory proteins. GvpD is involved in the regulation of gas vesicle formation and functions as a repressor through the interaction and the breakdown induction of the transcriptional activator GvpE. This domain includes the P-loop and the basic region 1 (bR1, an arginine-rich region) which are essential for GvpD repressive function.
