A DNA Algorithm for Comparative Modeling of Protein Structure

ZHAO Dongming,QIANG Xiaoli,LIU Xiangrong School of Electronic Engineering and Computer Science,Peking University,Beijing 100871  
A new algorithm—DNA computing is introduced into protein structure predication.A DNA computing method of comparative model of protein structure is proposed when the similarity is low between the protein structure and the templates.Each possible conformation of residue represents a strand of DNA sequence.In this way,a problem of protein prediction is transformed into an edge-weighted MWCP(maximal weight clique problem).A DNA algorithm is proposed using the DNA computing model of MWCP.The efficiency is proved by simulation result.
