CC   -!- FUNCTION: Chaperone for NapA, the catalytic subunit of the periplasmic
CC       nitrate reductase. It binds directly and specifically to the twin-
CC       arginine signal peptide of NapA, preventing premature interaction with
CC       the Tat translocase and premature export. {ECO:0000255|HAMAP-
CC       Rule:MF_02200}.
CC   -!- SUBUNIT: Interacts with the cytoplasmic NapA precursor.
CC       {ECO:0000255|HAMAP-Rule:MF_02200}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_02200,
CC       ECO:0000305}.
CC   -!- SIMILARITY: Belongs to the NapD family. {ECO:0000255|HAMAP-
CC       Rule:MF_02200}.
