They are solid, thinner filament structures (6-8 nm, in diameter) composed of a double-helical polymer of the protein actin. And microfilaments play a key role of in virtually all types of contractility and location of cells as well as motility within cells

18. The anticodon and/or the amino acid arms of a tRNA are key for a specific aminoacyl-tRNA synthetase to recognize This was revealed via: crystal structure determination of the synthetases complexed with their cognate tRNAs; sequence comparison of tRNAs binding to the same synthetase; and mutagenesis studies

Expression, Purification and Crystallization of the Mycobacterium Tuberculosis HSP16.3 Molecular Chaperone Background of Mycobacterium Tuberculosis HSP16.3 HSP16.3, a 16.3 kDa protein from Mycobacterium Tuberculosis, was originally identified as a prominent antigen (Kingston et al., 1987).

he relationship between structure and function reaches its ultimate expression in the chemistry of amino acids, peptides, and protein Amino acids are carboxylic acids that contain an amine function. Under cer- tain conditions the amine group of one molecule and the carboxyl group of a second can react, uniting the two amino acids by an amide bond. Amide(peptide)bond
