Precorrin-2 C20-methyltransferase

In enzymology, a precorrin-2 C20-methyltransferase (EC number|2.1.1.130) is an enzyme that catalyzes the chemical reaction

:S-adenosyl-L-methionine + precorrin-2 $ightleftharpoons$ S-adenosyl-L-homocysteine + precorrin-3A

Thus, the two substrates of this enzyme are S-adenosyl methionine and precorrin 2, whereas its two products are S-adenosylhomocysteine and precorrin 3A.

This enzyme belongs to the family of transferases, specifically those transferring one-carbon group methyltransferases. The systematic name of this enzyme class is S-adenosyl-L-methionine:precorrin-4 C20-methyltransferase. This enzyme participates in porphyrin and chlorophyll metabolism.

tructural studies

As of late 2007, two structures have been solved for this class of enzymes, with PDB accession codes PDB link|2E0K and PDB link|2E0N.
