Overview of GvpA cysteine variants. Ab initio protein prediction for gvpA1 (gas vesicle structural protein 1) from Halobacterium salinarum (Uniport: P08958) by I-TASSER (left side), and based on GvpA of Bacillus megaterium (PDB: 7R1C) (right side). Cysteines are marked in yellow. Surface colors indicate negative and positive electrostatic potentials contoured from 50 kT/e (blue) to –50 kT/e (red).
