NpSRII
This part is the NpSRII sensory rhodopsin.
Usage and Biology
NpSRII is a sensory rhodopsin identified in the archaea Natronomonas pharaonis.
Sensory rhodopsins are not pumps, but photoreceptors that respond to light and transmit the signal into the cell via a signaling cascade. For this, in N. pharaonis, NpSRI and NpSRII interact with the transducer proteins NpHtrI and NpHtrII, respectively [1]. NpHtrI and NpHtrII are homodimeric membrane proteins that have also a cytoplasmic histidine kinase domain responsible for initiating the signaling cascade that mediates chemotaxis. The interaction between the SR and their cognate Htr transducers are highly specific.
