What is the structure of enzyme amylase?
Primary structure of human alpha-amylase consists of 496 amino acid residues. A complete account is given in this site http://www.sas.upenn.edu/~ljn/NarkePeten… Secondary structure:- 33% helical – 20 helices, 165 amino acids. 18% beta sheet – 21 strands, 90 amino acids. Remainder is extended strands. All alpha-amylases are metalloenzymes and contain at least one Ca2+ per enzyme molecule. Essential for activity and stability http://216.109.125.130/search/cache?
