核酸双序列比对程序，可对DNA、RNA、蛋白质序列进行比对，结果为最优比对。-nucleic acid sequences than double the procedure, the DNA, RNA and protein sequences compared to Optimal results than the right.

A prograom clculated inter-helica angle between neighbor a-hlix of a given protein PDB file. Notice the helix should contain at least 5 amino acid.

核酸双序列比对程序，可对DNA、RNA、蛋白质序列进行比对，结果为最优比对-Nucleic acid pairwise sequence alignment procedures can DNA, RNA, protein sequences were compared, the result is the optimal alignment

SignalP 4.1 server predicts the presence and location of signal peptide cleavage sites in amino acid sequences from different organisms: Gram-positive prokaryotes, Gram-negative prokaryotes, and eukaryotes. The method incorporates a prediction of cle
