Prediction of protein functions from known genomic sequences is an important mission of bioinformatics. One approach is to classify proteins into functional categories. We have therefore developed a method based on protein domain composition and the maximum likelihood estimation (MLE) algorithm to classify proteins according to functions. Using the Saccharomyces cerevisiae genome, we compared the effectiveness of the MLE approach with that of an intuitive and simple method. The MLE method outperformed the simple method, achieving an estimated specificity of 75.45 % and an estimated sensitivity of 40.26 %. These results indicate that domain is an important feature of proteins and is closely related to protein function. 相似文献

本文论述的压力测试仪,可直接显示被测压力。它以单片机为核心,全部采用CMOSIC,硬件简单,功耗低,可靠性高。它同钢弦式传感器配套使用,采用测周期法对传感器输出的频率信号进行测量,速度快、误差小。采用一种新颖的方法处理传感器初频漂移问题。此外,因为数据处理以二进制浮点数进行,故对以十进制浮点数表示的传感器常数到二进制浮点数之间的转换进行了论述。实践表明,具有高性能价格比的单片机是开发智能仪表的理想器件。 相似文献

Leptospirosis, a serious and contagious zoonotic bacterial disease that havocs livers and kidneys in hu-mans and some animals, occurs in both urban and rural environments worldwide. It is caused by the genus lep- tospira, a corkscrew-shaped bacterium[1]. Though the genomes of Leptospira interrogans serovars Lai strain lai[2] and Leptospira interrogans serovars Copenhageni strain L1-130[3] were recently sequenced and many molecular and cellular studies on leptospires have been conducted, the … 相似文献
