Structural highlights

Function

DESK_BACSU Member of the two-component regulatory system DesR/DesK, responsible for cold induction of the des gene coding for the Delta5 acyl-lipid desaturase. Acts as a sensor of the membrane fluidity. Probably activates DesR by phosphorylation.^{[1] [2] [3] [4] [5]}
