The methyl-accepting transducer protein HtrI is functionally associated with the photoreceptor sensory rhodopsin I in the archaeon Halobacterium salinarium.

Abstract excerpt

We have investigated the functional relationship between two proteins involved in the photosensory system of the archaeon Halobacterium salinarium: the photoreceptor sensory rhodopsin I (SRI) and the halobacterial transducer rhodopsin I (HtrI), which has been proposed to be the putative signal transducer of SRI, by genomic DNA analysis of two independent SRI negative mutants, Pho81 and D1. Southern and PCR...
