Maximizing Gene Expression focuses on prokaryotic and eukaryotic gene expression. The book first discusses E. coli promoters. Topics include structure analysis, steps in transcription initiation, structure-function correlation, and regulation of transcription initiation. The text also highlights yeast promoters, including elements that select initiation sites, transcription regulation, regulatory proteins, and upstream promoter elements. The text also describes protein coding genes of higher eukaryotes; instability of messenger RNA in bacteria; and replication control of the ColE1-type plasmids. The text then describes translation initiation, including the translation of prokaryotes and eukaryotes. The book puts emphasis on the selective degradation of abnormal proteins in bacteria. Topics include proteins rapidly hydrolyzed in E. coli; intracellular aggregates of abnormal polypeptides; energy requirement and pathway for proteins; proteolytic enzymes in E. coli; and regulation of ion expression. The text also highlights the detection of proteins produced by recombinant DNA techniques and mechanism and practice. The book is a good source of information for readers wanting to study gene expression.
