An unexpected but important aspect of the relationship deduced here is that the main eubacterial phyla are related to each other linearly rather than in a tree-like manner, suggesting that the major evolutionary changes within Bacteria have taken place in a directional manner.

A global alignment of all available sequences for the 90-kD heat shock protein (Hsp90) family indicates that the cytosolic and the endoplasmic reticulum (ER) resident forms of Hsp90 constitute paralogous gene families which arose by a gene duplication event that took place very early in the evolution of eukaryotic cells.
Adenosine kinase and ribokinase – the RK family of proteins
The topics covered include descriptions of the primary and three-dimensional structures of AK and RK, their phylogenetic relationships, biochemical aspects ofThese enzymes including their reaction mechanisms and ionic requirements, and also work on certain inhibitors of these enzymes.
Primary structure of a human mitochondrial protein homologous to the bacterial and plant chaperonins and to the 65-kilodalton mycobacterial antigen
The observed high degree of homology between human P1 and mycobacterial antigen also suggests the possible involvement of this protein in certain autoimmune diseases.
Immunoelectron microscopic localization of the 60-kDa heat shock chaperonin protein (Hsp60) in mammalian cells.
The subcellular distribution of the 60-kDa heat shock protein (Hsp60) was examined in a variety of mammalian cells and tissues by immunogold electron microscopy employing six different monoclonal and polyclonal antibodies that are specific for Hsp60, providing evidence that at least partial mitochondrial import of HSp60 is necessary for its maturation.

Investigating the mechanisms of the involvement of immune reactions to hsp65/60 in initiating atherosclerosis found endothelial cells stressed by high temperature or certain cytokines express hsp60 in the cytoplasm and on their surfaces, and these cells were susceptible to complement-dependent lysis by hsp 60-specific antibody.

The water-deficit stress- and red-rot-related genes in sugarcane
Real-time reverse transcription–PCR profiling of selected EST clusters identified several sugarcane clusters that show differential expression in response to biotic and abiotic stress conditions, and these clusters are good candidates for in-depth analysis to elucidate stress-responsive pathways in Sugarcane.
