HSSP (Homology-derived Secondary Structure of Proteins) is a database that combines structural and sequence information about proteins. This database has the information of the alignment of all available homologs of proteins from the PDB database As a result of this, HSSP is also a database of homology-based implied protein structures.
In biology, homology is similarity in anatomical structures or genes between organisms of different taxa due to shared ancestry, regardless of current functional differences. Evolutionary biology explains homologous structures as retained heredity from a common ancestor after having been subjected to adaptive modifications for different ...
Since C −1 = 0, every 0-chain is a cycle (i.e. Z 0 = C 0); moreover, the group B 0 of the 0-boundaries is generated by the three elements on the right of these equations, creating a two-dimensional subgroup of C 0. So the 0th homology group H 0 (S) = Z 0 /B 0 is isomorphic to Z, with a basis given (for example) by the image of the 0-cycle (v 0).
A protein superfamily is the largest grouping of proteins for which common ancestry can be inferred (see homology). Usually this common ancestry is inferred from structural alignment [ 1 ] and mechanistic similarity, even if no sequence similarity is evident. [ 2 ]
Sequence homology is the biological homology between DNA, RNA, or protein sequences, defined in terms of shared ancestry in the evolutionary history of life. Two segments of DNA can have shared ancestry because of three phenomena: either a speciation event (orthologs), or a duplication event (paralogs), or else a horizontal (or lateral) gene ...
In contrast, the latest research focuses on young adults ages 21–25 – an important age group. Chronic diet-associated conditions, like type 2 diabetes or obesity, often take decades to develop ...
A generator for the fundamental group is the closed curve obtained by projecting any curve connecting antipodal points in down to . The projective n {\displaystyle n} -space is compact, connected, and has a fundamental group isomorphic to the cyclic group of order 2: its universal covering space is given by the antipody ...
