- ATP + L-arabinose ADP + beta-L-arabinose 1-phosphate
Thus, the two substrates of this enzyme are ATP and L-arabinose, whereas its two products are ADP and beta-L-arabinose 1-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:L-arabinose 1-phosphotransferase. This enzyme is also called L-arabinokinase (phosphorylating). This enzyme participates in nucleotide sugars metabolism.
