CC   -!- FUNCTION: Catalyzes the phosphorylation of undecaprenol in vitro, which
CC       is probably the physiological substrate. Exhibits no detectable
CC       activity against other substrates such as monoacylglycerol, ceramide,
CC       or diacylglycerol (DAG). Appears indispensable for the maintenance of
CC       spore stability and viability in B.subtilis.
CC       {ECO:0000269|PubMed:17535816}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=di-trans,octa-cis-undecaprenol + ATP = di-trans,octa-cis-
CC         undecaprenyl phosphate + ADP + H(+); Xref=Rhea:RHEA:28122,

CC         ChEBI:CHEBI:61216, ChEBI:CHEBI:456216; EC=2.7.1.66;
CC         Evidence={ECO:0000269|PubMed:17535816};
CC   -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000305}; Multi-pass membrane
CC       protein {ECO:0000305}. Note=Localized in both lateral and septal
CC       membranes. {ECO:0000269|PubMed:15743965}.
CC   -!- INDUCTION: Mainly expressed during the vegetative phase of growth.
CC       {ECO:0000269|PubMed:12923107}.
CC   -!- DISRUPTION PHENOTYPE: Cells lacking this gene exhibit an abnormal
CC       cortex structure in mutant endospores 6 hours after the onset of
CC       sporulation, an indication of cortex degeneration. In addition, they
CC       display a significant decrease in the dipicolinic acid content of
CC       mutant spores. {ECO:0000269|PubMed:12923107}.
CC   -!- SIMILARITY: Belongs to the bacterial diacylglycerol kinase family.
CC       {ECO:0000305}.
CC   -!- CAUTION: Was originally thought to be a diacylglycerol kinase.
CC       {ECO:0000305|PubMed:12923107}.
CC   -!- SEQUENCE CAUTION:
CC       Sequence=AAA70044.1; Type=Erroneous initiation; Note=Extended N-terminus.; Evidence={ECO:0000305};
CC       Sequence=BAA12480.1; Type=Frameshift; Evidence={ECO:0000305};
