Function
[PHNJ_ECOLI] Catalyzes the breakage of the C-P bond in alpha-D-ribose 1-methylphosphonate 5-phosphate (PRPn) forming alpha-D-ribose 1,2-cyclic phosphate 5-phosphate (PRcP).[1] [PHNG_ECOLI] Together with PhnH, PhnI and PhnL is required for the transfer of the ribose triphosphate moiety from ATP to methyl phosphonate.[2] [PHNI_ECOLI] Together with PhnG, PhnH and PhnL is required for the transfer of the ribose triphosphate moiety from ATP to methyl phosphonate. PhnI alone has nucleosidase activity, catalyzing the hydrolysis of ATP or GTP forming alpha-D-ribose 5-triphosphate and adenine or guanine, respectively.[3] [PHNH_ECOLI] Together with PhnG, PhnI and PhnL is required for the transfer of the ribose triphosphate moiety from ATP to methyl phosphonate.[4]
