S-adenosyl-L-homocysteine is an amino acid derivative used in several metabolic pathways in the organism E.Coli.
Pathways
In Pathway Reactions as a Product
Chemotactic Signal Transduction System
a protein-L-glutamate + S-adenosyl-L-methionine -> a protein-L-glutamate--O5-methyl-ester + S-adenosyl-L-homocysteine
Cyclopropane Fatty Acid (CFA) Biosynthesis
a phospholipid olefinic fatty acid + S-adenosyl-L-methionine -> a phospholipid cyclopropane fatty acid + S-adenosyl-L-homocysteine
Heme Biosynthesis I
2 S-adenosyl-L-methionine + uroporphyrinogen-III -> 2 S-adenosyl-L-homocysteine + precorrin-2
Menaquinone Biosynthesis
demethylmenaquinone-8 + S-adenosyl-L-methionine = menaquinone-8 + S-adenosyl-L-homocysteine
Ubiquinone Biosynthesis
2-octaprenyl-6-methoxy-1,4-benzoquinone + S-adenosyl-L-methionine = 2-octaprenyl-3-methyl-6-methoxy-1,4-benzoquinone + S-adenosyl-L-homocysteine
2-octaprenyl-6-hydroxyphenol + S-adenosyl-L-methionine = 2-octaprenyl-6-methoxyphenol + S-adenosyl-L-homocysteine
3-demethylubiquinone-8 + S-adenosyl-L-methionine = ubiquinone-8 + S-adenosyl-L-homocysteine
