Figure 3From: An improved genetic system for bioengineering buoyant gas vesicle nanoparticles from HaloarchaeaGvpC protein sequence and engineering sites. The amino acid sequence of GvpC of Halobacterium sp. NRC-1 is shown with conserved residues (vertical bars) in the eight imperfect repeats. The GvpC segments used in this study are labeled C1, C2, C3 and C4 at the C-terminal end. The position of the κ insertion in the gvpC mutant is labeled ‘κ’.Back to article page
