CC -!- FUNCTION: Photosensitive kinase that is involved in increased bacterial
CC virulence upon exposure to light. Once ejected from an infected animal
CC host, sunlight acts as an environmental signal that increases the
CC virulence of the bacterium, preparing it for infection of the next
CC host. This photoreceptor protein is directly related to the bacterium's
CC survival and replication within host macrophages (By similarity).
CC {ECO:0000250}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=ATP + protein L-histidine = ADP + protein N-phospho-L-
CC histidine.; EC=2.7.13.3;
CC -!- PTM: FMN binds covalently to cysteine after exposure to blue light and
CC this bond is spontaneously broken in the dark. {ECO:0000250}.
CC -!- SEQUENCE CAUTION:
CC Sequence=AAN33777.1; Type=Erroneous initiation; Evidence={ECO:0000305};
CC Sequence=AEM20054.1; Type=Erroneous initiation; Note=Truncated N-terminus.; Evidence={ECO:0000305};
