B. Any process that modulates the frequency, rate or extent of ATP-dependent RNA helicase activity.
C. Any process that modulates the frequency, rate or extent of deacetylase activity.
D. Any process that modulates the frequency, rate or extent of hydrolase activity, the catalysis of the hydrolysis of various bonds, e.g. C-O, C-N, C-C, phosphoric anhydride bonds, etc. Hydrolase is the systematic name for any enzyme of EC class 3.
