In [[enzymology]], a '''loganate O-methyltransferase''' ({{EC number|2.1.1.50}}) is an [[enzyme]] that [[catalysis|catalyzes]] the [[chemical reaction]]

:S-adenosyl-L-methionine + loganate <math>\rightleftharpoons</math> S-adenosyl-L-homocysteine + loganin

Thus, the two [[substrate (biochemistry)|substrates]] of this enzyme are [[S-Adenosyl methionine|S-adenosyl methionine]] and [[loganate]], whereas its two [[product (chemistry)|products]] are [[S-adenosylhomocysteine]] and [[loganin]].

This enzyme belongs to the family of [[transferase]]s, specifically those transferring one-carbon group methyltransferases.  The systematic name of this enzyme class is '''S-adenosyl-L-methionine:loganate 11-O-methyltransferase'''. Other names in common use include '''loganate methyltransferase''', and '''S-adenosyl-L-methionine:loganic acid methyltransferase'''.  This enzyme participates in [[indole and ipecac alkaloid biosynthesis]].
