Pathway Description
Hydrogen Sulfide Biosynthesis I
Escherichia coli
Metabolic Pathway
Many bacteria can produce hydrogen sulfide, which can be used as defense system against antibiotics and oxidative stress. This pathway is one of the hydrogen sulfide biosynthesis pathways (totally two). L-Cysteine is transported by L-cysteine ABC transporter and convert to 3-mercaptopyruvic acid by facilitation of aspartate aminotransferase. 3-Mercaptopyruvic acid is later catalyzed to form pyruvic acid and hydrogen sulfide by 3-mercaptopyruvate sulfurtransferase.
