IUBMB Enzyme Nomenclature


Accepted name: adenosine tuberculosinyltransferase

Reaction: tuberculosinyl diphosphate + adenosine = 1-tuberculosinyladenosine + diphosphate

Glossary: tuberculosinyl diphosphate = halima-5,13-dien-15-yl diphosphate

Other name(s): Rv3378c (locus name)

Systematic name: tuberculosinyl-diphosphate:adenosine tuberculosinyltransferase

Comments: The enzyme, characterized from the bacterial pathogen Mycobacterium tuberculosis, produces 1-tuberculosinyladenosine, an unusual terpene nucleoside that acts as a phagolysosome disruptor by neutralizing the pH, resulting in swelling of the lysosome and obliteration of its multilamellar structure.
