ID   2.7.1.239
DE   alpha-D-ribose-1-phosphate 5-kinase (ATP).
CA   alpha-D-ribose 1-phosphate + ATP = ADP + alpha-D-ribose 1,5-bisphosphate
CA   + H(+).
CC   -!- The enzyme, characterized from the halophilic archaeon Halopiger
CC       xanaduensis, participates in a non-carboxylating pentose bisphosphate
CC       pathway for nucleoside degradation, which is found in some halophilic
CC       archaea. cf. EC 2.7.1.212.
