CC -!- FUNCTION: Co-chaperone involved in the maturation of iron-sulfur
CC cluster-containing proteins. Seems to help targeting proteins to be
CC folded toward HscA. {ECO:0000255|HAMAP-Rule:MF_00682}.
CC -!- SUBUNIT: Interacts with HscA and stimulates its ATPase activity.
CC Interacts with IscU. {ECO:0000255|HAMAP-Rule:MF_00682}.
CC -!- SIMILARITY: Belongs to the HscB family. {ECO:0000255|HAMAP-
CC Rule:MF_00682}.
