Soluble guanylyl cyclase

Soluble guanylyl cyclase is the only known receptor for nitric oxide, NO. It is soluble, i.e. completely intracellular. Most notably, this enzyme is involved in vasodilation. In humans, it is encoded by the genes GUCY1A2, GUCY1A3, GUCY1B2 and GUCY1B3. It is classified under EC number 4.6.1.2.

                                     

TRNA-intron endonuclease

tRNA-intron lyase is an enzyme. This enzyme catalyses the following chemical reaction pre-tRNA ⇌ {\displaystyle \rightleftharpoons } a 3-half-tRNA molecule with a 5-OH end + a 5-half-tRNA molecule with a 2.3-cyclic phosphate end + an intron with a 2.3-cyclic phosphate and a 5-hydroxyl terminus This enzyme catalyses the final stage in the maturation of tRNA molecules. Its systematic name is pretRNA lyase intron-removing; cyclic-2.3-phosphate-forming.
