2.1.1.349 |
Accepted name: |
toxoflavin synthase |
Reaction: |
(1) S-adenosyl-L-methionine + 1,6-didemethyltoxoflavin = S-adenosyl-L-homocysteine + reumycin (2) S-adenosyl-L-methionine + reumycin = S-adenosyl-L-homocysteine + toxoflavin |
Glossary: |
reumycin = 1-demethyltoxoflavin
toxoflavin = 1,6-dimethylpyrimido[5,4-e][1,2,4]triazine-5,7(1H,6H)-dione |
Other name(s): |
toxA (gene name) |
Systematic name: |
S-adenosyl-L-methionine:1,6-didemethyltoxoflavin N1,N6-dimethyltransferase (toxoflavin-forming) |
Comments: |
The enzyme is a dual-specificity methyltransferase that catalyses the last two steps of toxoflavin biosynthesis. Toxoflavin is a major virulence factor of several bacterial crop pathogens. |
