SYSTEMATIC NAME
IUBMB Comments
(2Z,6E)-farnesyl-diphosphate diphosphate-lyase [cyclizing, (+)-beta-caryophyllene-forming]
A multifunctional enzyme which also converts the (+)-beta-caryophyllene to (+)-caryolan-1-ol (see EC 4.2.1.138, (+)-caryolan-1-ol synthase). cf. EC 4.2.3.57 (-)-beta-caryophyllene synthase.

LITERATURE
Mg2+
-
more than 5 mM MgCl2 is required for maximum activity. The enzyme reaction is unable to proceed without MgCl2
Mn2+
-
38% activity (relative to the activity in the presence of Mg2+) is retained in the presence of 5 mM Mn2+
additional information
-
no activity is observed for Fe2+, Co2+, Zn2+, Ni2+, or Cu2+
