LITERATURE
IMAGE
Ca2+
promotes the hydrolytic activity but inhibits the synthetic activity of the enzyme
Co2+
promotes the hydrolytic activity but inhibits the synthetic activity of the enzyme
deoxycholic acid
complete inhibition of the hydrolytic and synthetic activity
dimethoxyethane
addition of 5% of DME strongly promoted the activity, further increasing the DME concentrations progressively inhibited synthetic activity
DMSO
low concentrations of DMSO, up to a maximum at 10%, enhance synthetic activity, while higher concentrations inhibit
Fe2+
promotes the hydrolytic activity but inhibits the synthetic activity of the enzyme
Mg2+
promotes the hydrolytic activity but inhibits the synthetic activity of the enzyme
Ni2+
promotes the hydrolytic activity but inhibits the synthetic activity of the enzyme
Sn2+
-
10 mM, strong
taurodeoxycholate
complete inhibition of the hydrolytic and synthetic activity
Triton X-100
activates the hydrolytic reaction, best at 0.5% w/v, but inhibits the synthetic reaction
