چکیده
The study used various screening techniques, clustering, decision tree and generalized rule induction (association) (GRI) models and molecular phylogenic relationship to search for patterns of halophilicy and tofind features contribute to halolysin salt stability. We found that Met was the sole N-terminal amino acid inhalolysin proteins, whereas other amino acids found at that position of other proteases and termitase. Eightythree protein features were shown to be important in feature selection modeling, and just one peer group with an anomaly index of 2.42 declined to 1.87 after being run using only important selected features. The depth ofthe trees generated by various decision tree models varied from 1 to 5 branches. Compared to datasets withoutfeature selection the number of peer groups in clustering models was reduced significantly (p< 0.05). In most decision tree models, the frequency of Gly - Gly was the most important feature for decision tree rule sets and this feature was used in antecedent to support the rules in most GRI association rules. Significant differences (p < 0.001) found in charged amino acids between halolysin and other proteins with more Asp and Glu in halolysin proteins, while more hydrophobic residues and aliphatic amino acids were found in other proteasesکلیدواژه ها

COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.
کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
