The two methionine adenosyl transferases in Saccharomyces cerevisiae: Evidence for the existence of dimeric enzymes

  • Published:
Molecular and General Genetics MGG Aims and scope Submit manuscript

Summary

In Saccharomyces cerevisiae either of the two genes SAM1 and SAM2 is able to produce a functional methionine adenosyl transferase (MATI and MATII). In a wild-type strain, MATI and MATII are present in dimeric forms: MATI-MATI, MATII-MATII and perhaps MATI-MATII. A hypothesis is presented to explain the possible role of these different forms of methionine adenosyl transferase in S. cerevisiae.
