Identification and characterization of an S-adenosyl-L-methionine: delta 24-sterol-C-methyltransferase cDNA from soybean.


In plants, the dominant sterols are 24-alkyl sterols, which play multiple roles in plant growth and development, i.e. as membrane constituents and as precursors to steroid growth regulators such as brassinosteroids. The initial step in the conversion of the phytosterol intermediate cycloartenol to the 24-alkyl sterols is catalyzed by S-adenosyl-L-methionine… (More)
