In
enzymology, precorrin-3B C17-methyltransferase (EC 2.1.1.131) is an enzyme that catalyzes the chemical reaction
- S-adenosyl-L-methionine + precorrin-3B S-adenosyl-L-homocysteine + precorrin-4
The two
S-adenosylhomocysteine and precorrin 4
.
This enzyme belongs to the family of
ring-contracts so that the corrin
core of the vitamin is formed.
