Calmodulin-like ( CML ) is one of the important Ca 2+  sensors, which plays an role in plant growth and development stress response. In this study, melon Cucumismelo  L.) genomic data was used to identify CML protein family using bioinformatics methods, its physical chemical properties, location information, gene structure, phylogeny, promoter were analyzed. The results showed th...

background: dihydropyrimidinase related proteins (drps) have known homologous to the collapsing response mediator proteins (crmps). the drp gene family has comprised four members, drp 1, 2, 3, and 4, all out of which have considered to be involved in axonal outgrowth and path-finding. methods: the protein has extracted from tumor, normal brain tissues, and then the protein purity has evaluated ...

background pe5 is a member of the pe protein family whose precise function is yet to be understood. there are about 100 members of the pe family proteins in mycobacterium tuberculosis. these glycine- and alanine-rich proteins consist of proline-glutamate motifs at their n-termini and may be implicated in pathogenesis of the bacilli. objectives we aimed to clone and over-express the rv0285 codin...

Based on the SYSTERS protein family database, we present taxon-related protein family frequencies and distributions. A set of taxon-related protein families is a subset of the whole family set with respect to one taxon, where taxon is not restricted to the species level but may be any rank in the taxonomy. We examine eight ranks in the lineages of seven organisms. A strong linear correlation is...

In the postgenomic era, one of the most interesting and important challenges is to understand protein interactions on a large scale. The physical interactions between protein domains are fundamental to the workings of a cell: in multi-domain polypeptide chains, in multi-subunit proteins and in transient complexes between proteins that also exist independently. To study the large-scale patterns ...

A possible explanation for the frequent occurrence of power-law distributions in biology and elsewhere comes from an analysis of the interplay between random time evolution and random observation or killing time. If the system population or its topological parameters grow exponentially with time, and observations on the system correspond to stopping the evolution at an exponentially distributed...

2 Introduction Protein sequences are known to evolve much faster than structures. Pairs of distantly homologous proteins with very low sequence similarity may still share very similar folds and functions. One example of well-preserved structural motifs is given by specific three-dimensional orientations of amino acid residues in the active site of a protein, which are responsible for protein’s ...
