53 catalytic interaction between enzyme-coenzyme complex and
substrate (VENNESLAND and WESTHEIMER 1954; VENNESLAND 1955,1956;
GUTFREUND 1959) have all been the subject of numerous excellent and
exhaustive reviews. These topics, therefore, will not be treated in
extenso here. The present summary will deal instead with more
recent observations on the pyridine nucleotide dependent
dehydrogenases which have necessitated a re-examination of their
function and structure in the light of new information concerning
their composition. The new compositional characterization of these
enzymes dates from 1955 [VALLEE and HOCH 1955 (a), (b), (c)] when
the DPN dependent alcohol dehydrogenase of bakers' yeast was
identified as a zinc metalloenzyme. Since then several other DPN
-dependent enzymes have been similady shown to contain zinc [VALLEE
1955, 1960 (a), (b)], and a number of DPN and TPN dependent
dehydrogenases have been tentatively identified as metalloenzymes
(VALLEE et al. 1956). Knowledge of the presence of zinc in these
enzymes has provided a new set of parameters for the study of these
systems. The metal in such systems retains much of the chemical
reactivity exhibited in the ionic form, modified by its
incorporation into the protein matrix. Since the metal is not only
a compositional constituent, but is also involved in the protein
structure and in the events of catalysis, its reactivity can be
used to advantage in exploring specific enzymatic sites, and the
general problems of biological catalysis.
