Tyrosine phosphorylation in plants could be performed only by dual-specificity kinases. Arabidopsis thaliana dual-specificity protein kinase (AtSTYPK) exhibited strong preference for manganese over magnesium for its kinase activity. The kinase autophosphorylated on serine, threonine and tyrosine residues and phosphorylated myelin basic protein on threonine and tyrosine residues. The AtSTYPK harbors manganese dependent serine/threonine kinase domain, COG3642. His248 and Ser265 on COG3642 are… CONTINUE READING
