The suggestion that the ethanol regulatory protein from Aspergillus has its evolutionary origin in a gene fusion between aldehyde and alcohol dehydrogenase genes (Hawkins AR, Lamb HK, Radford A, Moore JD, 1994, Gene 146:145-158) has been tested by profile analysis with aldehyde and alcohol dehydrogenase family profiles. We show that the degree and kind of similarity observed between these profiles and the ethanol regulatory protein sequence is that expected from random sequences of the same composition. This level of similarity fails to support the suggested gene fusion.
有人提出,来自曲霉的乙醇调节蛋白在进化上起源于醛脱氢酶基因和醇脱氢酶基因之间的基因融合(霍金斯·AR、兰姆·HK、拉德福德·A、摩尔·JD,1994年,《基因》146:145 - 158),我们通过醛脱氢酶和醇脱氢酶家族图谱分析对这一观点进行了验证。我们发现,这些图谱与乙醇调节蛋白序列之间观察到的相似程度和类型,与相同组成的随机序列所预期的情况相符。这种相似水平无法支持所提出的基因融合观点。
