The primary structure of a lectin isolated from the red alga Bryothamnion triquetrum was established by combination of Edman degradation of sets of overlapping peptides and mass spectrometry. It contains 91 amino acids and two disulphide bonds. The primary structure of the B. triquetrum lectin does not show amino acid sequence similarity with known plant and animal lectin structures. Hence, this protein may be the paradigm of a novel lectin family. 相似文献

一类非线性系统的稳定性 总被引:3,自引:0,他引:3
研究了一类非线性系统的输入输出稳定性问题,这类系统的特点是其模型为系统输出的线性拟函数。对非线性稳定性系统,利用稳定性的线性等价原理,提出了这一类非线性系统的稳定性判据;对非线性随机系统,给出了m阶均值意义下的稳定性定义,提出了一种二阶均值下的输入输出稳定性条件,给出了几个示例说明。 相似文献
