ATP dependent phosphorylation of adenosine and other related nucleoside analogs to monophosphate derivatives (PubMed:11115893). Essential to sustain methyl recycling (PubMed:17272833). adenosine + ATP = ADP + AMP + H(+) Inactivated by the begomovirus AL2 protein or the curtovirus L2 protein. Purine metabolism; AMP biosynthesis via salvage pathway; AMP from adenosine: step 1/1. Interacts with the begomovirus AL2 protein and the curtovirus L2 protein (PubMed:14615595). Interacts with KIN11 (PubMed:24498147). Widely expressed. Up-regulated during the lignification process in inflorescence stems. Phosphorylated by KIN11. Belongs to the carbohydrate kinase PfkB family.
