Abstract
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.
摘要
在酿酒酵母中，SAM1和SAM2这两个基因中的任何一个都能够产生功能性的甲硫氨酸腺苷转移酶（MATI和MATII）。在野生型菌株中，MATI和MATII以二聚体形式存在：MATI-MATI、MATII-MATII，或许还有MATI-MATII。本文提出了一个假设，以解释这些不同形式的甲硫氨酸腺苷转移酶在酿酒酵母中的可能作用。
