A hemerythrin-like domain in a bacterial chemotaxis protein.

Focuses on the immunoblotting of Desulfovibrio chemoreceptor genes expressed in a hemerythrin (Hr)-like domain. Presence of Hr protein in some marine invertebrates; Evidence of four-helix bundle structure in the C-terminal Hr-like domain; Discovery of Hr-like sequence motif at the C-terminus of the putative protein from a sulfate-reducing bacterium.
