Directed protein-evolution strategies generally make use of a link between a protein and the encoding DNA. In phage-display technology, this link is provided by fusion of the protein with a coat protein that is incorporated into the phage particle containing the DNA. Optimization of this link can be achieved by adjusting the signal sequence of the fusion. In a previous study, directed evolution of signal sequences for optimal display of the Taq DNA polymerase I Stoffel fragment on phage yielded signal peptides with a 50- fold higher incorporation of fusion proteins in phage particles. In this article, we show that for one of the selected signal sequences, improved display on phage can be generalized to other proteins, such as adenylate cyclases from Escherichia coli and Bordetella pertussis, and that this is highly dependent on short sequences at the C-terminus of the signal peptide. Further, the display of two enzymes on phage has been achieved and may provide a strategy for directing coevolution of the two proteins. These findings should be useful for display of large and cytoplasmic proteins on filamentous phage.
