1 | Since transphosphorylation of the two kinases is presumed to occur after receptor engagement we examined the phosphorylation by recombinant JAK3 of a peptide substrate corresponding to the JAK1 activation loop (KAIETDKEYYTVKD), which has two adjacent tyrosines. | Tyrosine | Janus kinase 1 | Homo sapiens |
2 | Kinetic analysis of the reactions of singly phosphorylated JAK1 activation loop peptides showed that phosphorylating the first or second tyrosine decreased the k(cat)/K(m) for the phosphorylation of the other 115- and 26-fold, respectively. | Tyrosine | Janus kinase 1 | Homo sapiens |
