Given each set of information which may include common name(s) and the reaction catalyzed, you are required to identify the main class of the specific enzyme described. Name: citryl-CoA synthetase Reaction: ATP + citrate + CoA = ADP + phosphate + (3S)-citryl-CoA Name: D-xylulose reductase Reaction: xylitol + NAD+ = D-xylulose + NADH + H+ Name: cellobiose phosphorylase Reaction: cellobiose phosphate = α-D-glucose 1-phosphate + D-glucose Name: carbonic anhydrase Reaction: H2CO3 = CO2 + H2O Other info: The enzyme catalyzes the reversible hydration of gaseous CO2 to carbonic acid, which dissociates to give hydrogencarbonate above neutral pH.
