Residue replacements were made at five positions (Arg-73, Asp-76, Tyr-87, Asp-106, and Asp-201) in the Halobacterium salinarium phototaxis receptor sensory rhodopsin I (SR-I) by site-specific mutagenesis. The sites were chosen for their correspondenc

Both sensory rhodopsin I (SR-I), a phototaxis receptor, and bacteriorhodopsin (BR), a light-driven proton pump, share residues which have been identified as critical for BR functioning. This includes Asp76, which in the case of bacteriorhodopsin (Asp

Coenzyme F430 is a Ni(II)-containing corphinoid which was first isolated from the cells of methanogenic archaebacteria in 1978. The cofactor F430 is responsible for the conversion of CO2 into CH4 in the methanogenic process. Starting from the first s

Pyranine (8-hydroxyl-1,3,6-pyrene-trisulfonate) was used as a pH-probe to test whether there is a light-induced proton release to the bulk phase during the photochemical reaction cycle of sensory rhodopsin-I (SR-I). We conclude that the retinylidene

A modified agar bottle plate is described for the cultivation and isolation of strict anaerobes. The design, which has an additional port for gas intake, permits easier streaking as well as picking of colonies, since no gassing probe is required. Wit
