RT   sporulation in Bacillus subtilis.";
RL   J. Bacteriol. 184:5545-5553(2002).
CC   -!- FUNCTION: Essential for the phosphorelay during initiation of
CC       sporulation. May control the level of phosphorylated spo0A through
CC       spo0E activity during sporulation. {ECO:0000269|PubMed:12270811}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm. Note=In the vegetative phase,
CC       localized throughout the periphery of the cell and the division septum.
CC       In the sporulation stages, fluorescence of the YaaT-GFP fusion protein
CC       was observed as two dots at the sides of an asymmetric septum and at
CC       the edges of the forespore.
