Isotuberculosinol synthase (EC 3.1.7.9, Rv3378c) is an enzyme with systematic name tuberculosinyl diphosphate diphosphohydrolase (isotuberculosinol forming). [1] [2] This enzyme catalyses the following chemical reaction

tuberculosinyl diphosphate + H2O (13S)-isotuberculosinol + diphosphate

This enzyme is present in species of Mycobacterium that cause tuberculosis.

Mycolic acids are long fatty acids found in the cell walls of Mycobacteriales taxon, a group of bacteria that includes Mycobacterium tuberculosis, the causative agent of the disease tuberculosis. They form the major component of the cell wall of many Mycobacteriales species. Despite their name, mycolic acids have no biological link to fungi; the name arises from the filamentous appearance their presence gives Mycobacteriales under high magnification. The presence of mycolic acids in the cell wall also gives Mycobacteriales a distinct gross morphological trait known as "cording". Mycolic acids were first isolated by Stodola et al. in 1938 from an extract of M. tuberculosis.

In molecular biology, YgbB is a protein domain. This entry makes reference to a number of proteins from eukaryotes and prokaryotes which share this common N-terminal signature and appear to be involved in terpenoid biosynthesis. The YgbB protein is a putative enzyme thought to aid terpenoid and isoprenoid biosynthesis, a vital chemical in all living organisms. This protein domain is part of an enzyme which catalyses a reaction in a complex pathway.

Isotuberculosinol, also called nosyberkol or edaxadiene is a diterpene molecule produced by the bacterium Mycobacterium tuberculosis, the causative agent of TB, which aids in its pathogenesis. Isotuberculosinol functions by preventing maturation of the host-cell phagosome in which the bacterium lives. Maturation of the phagosome would enable it to kill the bacterium. Mutations in genes involved in the biosynthetic pathway of nosyberkol result in normal development of the phagosome and reduction of mycobacterial infection. These biosynthetic genes include isotuberculosinol synthase.
