Immunological. , and these are known as "isoenzymes" or "isozymes". For example: Lactate Dehydrogenase (LDH) The LDH from the muscle and from the heart appears to be different from one another and generally contains two components Hand M. However five isoenzymes have been isolated,and they are designated as H4, H3M, H2M 2 , HM3 and M 4, The lactate dehydrogenase of the skeletal muscle is predominant M4 while in case of the cardiac muscle it is H4, The enzyme lactate dehydrogenase (LDH) catalyses the transfer of two electrons and one hydrogen ion from lactate to NAD+.
Till the separated particle form a discrete bandslzones. (Fig. 6) which are spaced according to the relative velocities of particles. It is necessary that centrifugation be terminated before any of the zone reaches bottom of the centrifuge tube. This method is useful for separation of enzymes, RNADNA hybrids, Ribosomal subunits, subcellular organelles, polysomes and lipoprotein fractions. Protein Proteln . 00 E u ~ ~ 'Vi c . 80 RNA Fig. 6 : Density gradient centrifugation -52 - 2. College Biochemistry - VI Isopycnic (Equilibrium Density Gradient) Centrifugation This method depends solely on the buoyant densities of particles to be separated and not on their size/shape.
Since substrate and inhibitor combine at different site, formation of both EI and ES complexes take place. It interact specifically with hydroxyl groups of serine residues of several hydroxylic enzymes. -29- Enzymes E + P lodoacetate is an alkylating agent that specifically binds to the sulphydryl groups of cystine and inactivates enzyme. Examples of Non-competitive inhibitors are heavy metal ions and organic molecules which binds reversibly with sulphydryl groups of cysteine residue in the enzymes.
