CC   -!- FUNCTION: Interacts with the SecY protein in vivo. May bind
CC       preferentially to an uncomplexed state of SecY, thus functioning either
CC       as a chelating agent for excess SecY in the cell or as a regulatory
CC       factor that negatively controls the translocase function.
CC       {ECO:0000255|HAMAP-Rule:MF_01104}.
CC   -!- SUBCELLULAR LOCATION: Cell inner membrane {ECO:0000255|HAMAP-
CC       Rule:MF_01104}; Peripheral membrane protein {ECO:0000255|HAMAP-
CC       Rule:MF_01104}; Cytoplasmic side {ECO:0000255|HAMAP-Rule:MF_01104}.
CC       Note=Loosely associated with the cytoplasmic side of the inner
CC       membrane, probably via SecY. {ECO:0000255|HAMAP-Rule:MF_01104}.
CC   -!- SIMILARITY: Belongs to the Syd family. {ECO:0000255|HAMAP-
CC       Rule:MF_01104}.
