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.
For the characterisation of this part an expression cassette was assembled and the results are presented on its page in Parts Registry: BBa_K4601205.
