BEHAVIOR OF BACTERIA--BIOCHEMISTRY AND GENETICS

这个项目的目的是发现细菌使用的机制， 对于被化学物质吸引或排斥（趋化性）：1） 化学品检测？ 我们现在知道，有化学感受器的功能。 2)细菌鞭毛是如何工作的？ 我们现在知道它们的功能是旋转， 就像螺旋桨一样，它们可以顺时针和逆时针旋转。 第三章 感觉到的信息是如何传递到鞭毛， 方向旋转，以使细菌朝向引诱剂，或 远离驱虫剂 我们发现了一组膜蛋白的甲基化， 甲基接受趋化蛋白（MCP），用于在 化学感受器和鞭毛。 这些蛋白质将被进一步研究 在未来的一年里。

The objective of this project is to discover the mechanisms that bacteria use for getting attracted or repelled by chemicals (chemotaxis): 1) How are the chemicals sensed? We now know that there are chemoreceptors for this function. 2) How do bacterial flagella work? We now know that they function by rotaating, like a propellor, and they can rotate both clockwise and counterclockwise. 3) How is the sensed information transmitted to the flagella to tell them in which direction to rotate, in order to bring the bacterium toward the attractants or away from the repellents? We discovered the methylation of a set of membrane proteins, the so-called methyl-accepting chemotaxis proteins (MCPs), that serve to communicate between the chemoreceptors and the flagella. These proteins will be further studied during the coming year.
