Schematic model of Cop5, Cr2c-Cyclop1 and designed chimeras. Colored modules indicate diverse protein domains of Cop5 (Cre02.g074150, 1501 aa) and Cr2c-Cyclop1 (Cre11.g467678, 1607 aa). Rhodopsin, rhodopsin domain; DHp, dimerization and histidine phosphotransferase domain; CA, catalytic and ATP-binding domain; RR, response regulator domain; GC, guanylyl cyclase domain. His kinase domain is labeled in dashed red boxes. In three chimeras C1, C2, and C3, the fusion positions were indicated by black line with triangle, amino acid sequences of the fusion constructs were highlighted with yellow color. H-box domain of the His Kinase is marked with red frame
