the hydrophobic proteins of plant plasma membrane still remain largely unknown.  for example in the arabidopsis genome, receptor-like kinases (rlks) are plasma membrane proteins, functioning as the primary receptors in the signaling of stress conditions, hormones and the presence of pathogens form a diverse family of over 610 genes. a limited number of these proteins have appeard in protein pro...

pyruvate kinase is a key enzyme in glycolytic pathway that catalyzes the transphosphorylation between phosphoenolpyruvate and adp to yield atp and pyruvate. geobacillus stearothermophillus has a stable pyruvate kinase with determined crystal structure that composed of four separate domains. given that limited proteolysis experiments can be successfully used to probe conformational features of p...

The α-kinases are a family of a typical protein kinases present in organisms ranging from protozoa to mammals. Here we report an autoinhibited conformation for the α-kinase domain of Dictyostelium myosin-II heavy chain kinase A (MHCK-A) in which nucleotide binding to the catalytic cleft, located at the interface between an N-terminal and C-terminal lobe, is sterically blocked by the side chain ...

To transmit the information inside the cell, one possibility is the action of an enzyme called kinase that phosphorylates other proteins. To study these enzymes, chemical compound synthesis was needed to know the function and the mechanism of activation. The major difficulty is creating a specific molecule for one kinase. In this study, we test the action of Rho-kinase inhibitors (HA-1077 and Y...

adenylate kinases (adk) are ubiquitous enzymes that contribute to the homeostasis of adeninenucleotides in living cells. in this study, the cloning of a cdna encoding an adenylate kinase from the filariaonchocerca volvulus has been described. using pcr technique, a 281 bp cdna fragment encoding part ofan adenylate kinase was isolated from an o. volvulus cdna library. use of this fragment as a p...

objective(s) inhibitors of p38 map kinase are considered as suitable target in the treatment of inflammatory diseases such as rheumatoid arthritis and bowel inflammatory diseases. the development of 5-alkylthio-1-aryl-2-(4-pyridinyl) triazoles as inhibitors of p38 map kinase is described. these are analogues of 4- pyridinyl imidazole p38 map kinase inhibitor reported by merck research laborator...

rho-kinase is an effector molecule of rhoa, a monomeric gtp-binding protein, and causes ca2+ sensitization through inactivation of myosin phosphatase. the major physiological functions of rho/rho-kinase cascade include contraction, proliferation and migration in cells.there are some excellent reviews about rho/rho-kinase signal pathway, most of which focus on the specific proteins of the pathwa...

Pyruvate kinase is a key enzyme in glycolytic pathway that catalyzes the transphosphorylation between phosphoenolpyruvate and ADP to yield ATP and Pyruvate. Geobacillus stearothermophillus has a stable pyruvate kinase with determined crystal structure that composed of four separate domains. Given that limited proteolysis experiments can be successfully used to probe conformational features of p...

to improve the specificity of biochemical markers of myocardial infarction (mi) a method to measure cardiac troponin-i (ctn-i) was developed. ctn-i is a protein unique to cardiac muscle and is released after mi. consecutive 150 patients admitted to the coronary care unit was studied. value of ctn-i was determined in all samples. ctn-i concentration in the mi patients group was increased compare...
