physiological function | the protein reversibly photoconverts between blue- and green-absorbing forms, and has diguanylate cyclase activity, which is enhanced 38fold by blue light compared with green light. The protein's relatively low affinity for Mg2+, which is essential for diguanylate cyclase activity, suggests thatMg2might also regulate cyclic-di-GMP signaling. Blue light irradiation under low temperature is responsible for Thermosynechococcus vulcanus cell aggregation, which is abolished when gene Tlr0924 is disrupted | Thermosynechococcus vestitus |
