This pathway appears to account for a major portion of methionine oxidation in vitro . Cultures of Streptomyces lincolnensis accumulated 3-methylthioacrylic acid in amounts directly related to the concentration of methionine in the medium. The first intermediate in the pathway may be the keto acid, which is then oxidatively decarboxylated to 3-methylthiopropionic acid. The purified 3-MTPA has antifungal activity in assays using F. oxysporum as a model fungus. Daily measurements of shoot and root length shows severe inhibition of seed germination and root and shoot development at concentrations above 12mg for partially purified extracts. 3-methylthiopropionic acid ethyl ester possesses potential anticarcinogenic properties by inducing differentiation in well-differentiated colon cancer cells. Treatment of RCM-1 cells for 4 days with 3-methylthiopropionic acid ethyl ester between the doses of 0.25 and 2 mM progressively increases the percent area occupied by duct structures relative to the control, and also induces an increase in the number and the maximum diameter of the ducts in each culture plate. | | 风险术语 | 34 - 引起灼伤。
