Thus, 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. The systematic name of this enzyme class is ATP:D-arabinose 5-phosphotransferase. This enzyme is also called D-arabinokinase (phosphorylating).
