CC -!- FUNCTION: A protein kinase that phosphorylates Ser and Thr residues.
CC Probably acts to suppress the effects of stress linked to accumulation
CC of reactive oxygen species. Probably involved in the extracytoplasmic
CC stress response. {ECO:0000255|HAMAP-Rule:MF_01497}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=ATP + L-seryl-[protein] = ADP + H(+) + O-phospho-L-seryl-
