Reaction: 4-coumaroyl-CoA + S-adenosyl-L-methionine = CoA + S-methyl-5-thioadenosine + N-(4-coumaroyl)-L-homoserine lactone
Glossary: S -methyl-5'-thioadenosine = 5'-deoxy-5'-(methylsulfanyl)adenosine
Other name(s): p-coumaryl-homoserine lactone synthase; RpaI
Systematic name: 4-coumaroyl-CoA:S-adenosyl-L-methionine trans-4-coumaroyltranserase (lactone-forming, methylthioadenosine-releasing)
Comments: The enzyme is found in the bacterium Rhodopseudomonas palustris, which produces N-(4-coumaroyl)-L-homoserine lactone as a quorum-sensing signal.
