Glossary: somaliensene B = (4S)-1-methyl-4-[(5E,9E,13E)-6,10,14-trimethylpentadeca-1,5,9,13-tetraen-2-yl]cyclohex-1-ene
Other name(s): stsC (gene name)
Systematic name: geranylfarnesyl-diphosphate diphosphate-lyase (cyclizing, somaliensene B-forming)
Comments: A sesterterpenoid synthase enzyme isolated from the bacterium Streptomyces somaliensis. The enzyme also produces somaliensene A (cf. EC 4.2.3.216, somaliensene A synthase).
