In enzymology a D-arabinokinase (EC 2.7.1.54) is an enzyme that catalyzes the chemical reactionATP + D-arabinose ADP + D-arabinose 5-phosphateThus the two substrates of this enzyme are ATP and D-arabinose whereas its two products are ADP and D-arabinose 5-phosphate.This enzyme belongs to the family of transferases specifically those transferring phosphorus-containing groups (phosphotransferases) with an alcohol group as acceptor.
