CC   -!- FUNCTION: Catalyzes the hydrolytic removal of ribose 5'-monophosphate
CC       from nitrogen N6-modified adenosines, the final step of bioactive
CC       cytokinin synthesis. Is involved in the synthesis of isopentenyladenine
CC       (iP) and 2-methylthio-iP (2MeS-iP), the most abundant cytokinins
CC       detected in M.tuberculosis lysates and supernatants. Is also able to
CC       convert trans-zeatin-riboside monophosphate (tZRMP) to trans-zeatin
CC       (tZ) in vitro; however, it may not be involved in the biosynthesis of
CC       this minor cytokinin in vivo. Accumulation of Rv1205 sensitizes
CC       M.tuberculosis to nitric oxide since cytokinin breakdown products
CC       synergize with NO to kill M.tuberculosis. Shows a slow AMP hydrolase
CC       activity, but is not able to hydrolyze ATP. Displays no lysine
CC       decarboxylase (LDC) activity (L-lysine conversion to cadaverine).
CC       {ECO:0000269|PubMed:25728768}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=H2O + N(6)-(dimethylallyl)adenosine 5'-phosphate = D-ribose 5-
CC         phosphate + N(6)-dimethylallyladenine; Xref=Rhea:RHEA:48560,

CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=9-ribosyl-trans-zeatin 5'-phosphate + H2O = D-ribose 5-
CC         phosphate + trans-zeatin; Xref=Rhea:RHEA:48564, ChEBI:CHEBI:15377,

CC   -!- BIOPHYSICOCHEMICAL PROPERTIES:
CC       Kinetic parameters:
CC         KM=5.59 uM for isopentenyladenine riboside monophosphate (iPRMP)
CC         {ECO:0000269|PubMed:25728768};
CC         KM=73.06 uM for AMP {ECO:0000269|PubMed:25728768};
CC         Note=kcat is 434.3 min(-1) for the hydrolysis of iPRMP. kcat is 2.27
CC         min(-1) for the hydrolysis of AMP. {ECO:0000269|PubMed:25728768};
CC   -!- SUBUNIT: Homodimer. {ECO:0000269|PubMed:25728768}.
CC   -!- PTM: Pupylated at Lys-74 by the prokaryotic ubiquitin-like protein Pup,
CC       which leads to its degradation by the proteasome. The proteasomal
CC       control of cytokinin synthesis is essential to protect M.tuberculosis
CC       against host-produced NO. {ECO:0000269|PubMed:25728768}.
CC   -!- DISRUPTION PHENOTYPE: Disruption of this gene suppresses the NO-
CC       sensitive phenotype of an mpa mutant, and therefore restores NO
CC       resistance to a proteasomal-degradation-deficient M.tuberculosis
CC       strain. In addition, the disruption mutation in Rv1205 partially
CC       rescues the defective growth of the mpa mutant in the lungs and spleens
CC       of mice. Strains lacking Rv1205 show a significant reduction in the
CC       amount of several cytokinins: iP levels are almost 30 times lower in
CC       mutant supernatants, along with a corresponding increase in the
CC       concentration of the cytokinin precursors, and the level of 2MeS-iP is
CC       reduced by almost two orders of magnitude in these strains.
CC       {ECO:0000269|PubMed:25728768}.
CC   -!- SIMILARITY: Belongs to the LOG family. {ECO:0000305}.
