[简答题] THE PARTY GENE Steven Benner jokingly calls himself a dilettante (业余艺术爱好者). A biochemist at the University of Florida in Gainesville, Benner learns a wide range of disciplines, from bioinformatics to astrobiology. His aim is to gain insight into the basic chemical rules that govern how life works — both here and, ultimately, on other planets. But although science drew his gaze to the skies, it was alcohol that brought him back down to Earth. Or, to be more exact, the enzymes that can both make and consume it. Alcohol dehydrogenase (脱氢酶) is best known as the enzyme (酶) that breaks down alcohol in the body, and as such it has been studied exhaustively. But Benner and other researchers in the field have now turned to its evolution, and their work is providing fresh insight into the puzzle of why some creatures, such as yeast, came to make alcohol and why so many others, including ourselves, can tolerate it. Alcohol dehydrogenase — ADH for short —
