the thermostability of the isozymes from pig heart ( h ) and muscle ( m ) lactate dehydrogenase ( l-lactate : nad+ oxidoreductase , ec 1.1.1.27 ) decreased in the order of h4 greater than m4 greater than h3m greater than hm3 greater than h2m2 , while the thermostability of the isozymes from guanidinated h4 and m4 increased as guanidinated h monomer was substituted by m monomer .
