This volume is the third in the series devoted to Antibiotics initiated
by Springer Verlag in 1967. The first two volumes were devoted to the
Mode of Action of Antibiotics and Biogenesis, respectively and were
received graciously. During the intervening years these two works have
been used often by research workers and students alike and have been
quoted extensively. Although a number of other excellent treatises on
antibiotics have appeared, the Springer series has set a standard for
thoroughness and quality that meets the need of the scientific
community. It is against this background that the present Editors set
about the preparation of a third volume in the Series on Antibiotics.
Since the appearance of Volume I, also dealing with Mechanism of Action,
tremendous strides have been made in the depth and breadth of our
knowledge of molecular biology, microbial chemistry and molecular
pharmacology and of their direct application to studies on the mode of
action of drugs. The field of molecular biology itself was in its
relative infancy during the preceding decade and the unique role played
by many anti- biotics in the development of our understanding of nucleic
acid synthesis and function and its relationship to protein synthesis
and cell physiology has led rapidly to a very precise, understanding of
how many of these same antibiotics inhibit susceptible cells.
