Glossary: tuberculosinyl diphosphate = halima-5,13-dien-15-yl diphosphate
Other name(s): Rv3378c
Systematic name: tuberculosinyl diphosphate diphosphohydrolase (isotuberculosinol forming)
Comments: Only found in species of Mycobacterium that cause tuberculosis. In addition, it also gives tuberculosinol in 1:1 mixture, cf EC 126.96.36.199, tuberculosinol synthase. The isotuberculosinol form was a 3:1 mixture of the 13S and1 3R forms, respectively.
