4.2.3.81 Mg2+ product formation is highest in the presence of the cofactor Mg2+ with product concentration peaking at 50 mM 677826 4.2.3.81 Mg2+ required 715604 4.2.3.81 Mg2+ required, enzyme CoTPS3 has the conserved aspartate-rich motif (DDXXD) and NSE/DTE motifs that chelate divalent metal ions, typically Mg2+, in the C-terminal domain 743000 4.2.3.81 Mg2+ when incubated in the presence of 10 mM Mg2+ the enzyme converts (E,E)-farnesyl diphosphate into alpha-santalene, beta-santalene and epi-beta-santalene,alpha-exo-bergamotene, as well as traces of alpha-farnesene and beta-farnesene. Incubations with Mn2+ yields mainly alpha-exo-bergamotene 715604 4.2.3.81 Mn2+ incubation in presence of Mn2+ yields mainly alpha-exo-bergamotene 715604 4.2.3.81 Mn2+ the assays with Mn2+ shows highest activity at 0.05 mM with 49% of the maximum product level 677826 4.2.3.81 Mn2+ when incubated in the presence of 10 mM Mg2+ the enzyme converts (E,E)-farnesyl diphosphate into alpha-santalene, beta-santalene and epi-beta-santalene,alpha-exo-bergamotene, as well as traces of alpha-farnesene and beta-farnesene. Incubations with Mn2+ yields mainly alpha-exo-bergamotene 715604
