Catalysis of the concomitant phosphorylation of threonine (T) and tyrosine (Y) residues in a Thr-Glu-Tyr (TEY) thiolester sequence in MAP kinases. It is a dual-specificity mitogen-activated protein kinase kinase and requires activation by the serine/threonine kinase, MAP kinase kinase kinase.

The chemical reactions involving a purine ribonucleotide, a compound consisting of ribonucleoside (a purine base linked to a ribose sugar) esterified with a phosphate moiety at either the 3' or 5'-hydroxyl group of its glycose moiety.

The process of coupling methionine to methionyl-tRNA, catalyzed by methionyl-tRNA synthetase. In tRNA aminoacylation, the amino acid is first activated by linkage to AMP and then transferred to either the 2'- or the 3'-hydroxyl group of the 3'-adenosine residue of the tRNA.

Catalysis of the phosphorylation and activation of MAP kinase kinases; each MAP kinase kinase can be phosphorylated by any of several MAP kinase kinase kinases.

Any process that activates or increases the activity of a cyclase.

The chemical reactions involving purine deoxyribonucleotide, a compound consisting of deoxyribonucleoside (a purine base linked to a deoxyribose sugar) esterified with a phosphate moiety at either the 3' or 5'-hydroxyl group of its glycose moiety.

The process of coupling phenylalanine to phenylalanyl-tRNA, catalyzed by phenylalanyl-tRNA synthetase. In tRNA aminoacylation, the amino acid is first activated by linkage to AMP and then transferred to either the 2'- or the 3'-hydroxyl group of the 3'-adenosine residue of the tRNA.

regulation of guanylate cyclase activity

Any process that modulates the frequency, rate or extent of guanylate cyclase activity.

The formation from simpler components of a purine ribonucleotide, a compound consisting of ribonucleoside (a purine base linked to a ribose sugar) esterified with a phosphate moiety at either the 3' or 5'-hydroxyl group of its glycose moiety.

The process of coupling proline to prolyl-tRNA, catalyzed by prolyl-tRNA synthetase. In tRNA aminoacylation, the amino acid is first activated by linkage to AMP and then transferred to either the 2'- or the 3'-hydroxyl group of the 3'-adenosine residue of the tRNA.
