objective diabetes mellitus is manifested by hyperglycaemia. different treatments such as diets and drugs are recommended for diabetes control. for various reasons in recent years traditional plant (herbal) therapies as prescribed by indigenous systems of medicine with different mechanisms have commonly been used. the digestive enzymes such as alpha glucosidase are among these herbal remedies. ...

recognition of rangeland species with the maximum efficiency and the minimum water usage is very important, since major parts of rangelands in iran are located in arid and semiarid climate. in addition, the rangeland improvement and management on the basis of transpiration rate of rangeland species in different climatic conditions has great importance. the goal of this research is comparison an...

The ASTRAL Compendium provides several databases and tools to aid in the analysis of protein structures, particularly through the use of their sequences. Partially derived from the SCOP database of protein structure domains, it includes sequences for each domain and other resources useful for studying these sequences and domain structures. The current release of ASTRAL contains 54,745 domains, ...

The structure of a protein can elucidate its function and its evolutionary history (seeChapters 18, 21 and 23). Extracting this information requires knowledge of the structure and its relationships with other proteins. These in turn require a general knowledge of the folds that proteins adopt and detailed information about the structure of many proteins. Nearly all proteins have structural simi...

A natural way to study protein sequence, structure, and function is to put them in the context of evolution. Homologs inherit similarities from their common ancestor, while analogs converge to similar structures due to a limited number of energetically favorable ways to pack secondary structural elements. Using novel strategies, we previously assembled two reliable databases of homologs and ana...

A web service for analysis of protein structures that are sequentially or non-sequentially similar was generated. Recently, the non-sequential structure alignment algorithm GANGSTA+ was introduced. GANGSTA+ can detect non-sequential structural analogs for proteins stated to possess novel folds. Since GANGSTA+ ignores the polypeptide chain connectivity of secondary structure elements (i.e. alpha...
