Secondary structure representation of proteins provides important information regarding protein general construction and shape. This representation is often used in protein similarity searching. Since existing commercial database management systems do not offer integrated exploration methods for biological data e.g. at the level of the SQL language, the structural similarity searching is usually performed...
The comparative analysis of structural and energy features of proteins can be a key to understand how proteins work and interact to each other in cellular reactions. Potential energy, which is a function of atomic positions in a protein structure, can be used to describe molecule's abilities to interact with other biological molecules. Potential energy characteristics are supportive in searching similar,...
The analysis of structural and energy features of proteins can be a key to understand how proteins work and interact to each other in cellular reactions. Potential energy is a function of atomic positions in a protein structure. The distributions of energy over each atom in protein structures can be very supportive for the studies of the complex processes proteins are involved in. Energy profiles...
In the paper, we discuss the usage of constant and fuzzy similarity awards while establishing an optimal alignment between energy characteristics of two compared protein energy profiles. Single protein energy profile is a set of energy characteristics of various types of energy. The energy profile is determined for a given protein structure. We use these profiles to find protein molecules of the same...
Protein structure has a big impact on the protein's activity in the living cells. Conformational modifications as an effect of biochemical reactions or environmental influences cause changes in the conformational energy distributions. Therefore, observations of the energy characteristics allow to detect structural changes of selected proteins. Moreover, having entire sets of energy characteristics...
