摘要
Background: The phage Mu Mor activator protein structure led to predictions of key amino acids needed for DNA binding. Results: Mutational analysis identified specific Mor amino acids needed for DNA binding and transcription activation. Conclusion: The properties of the mutants support the predictions from the structure. Significance: The Mor protein family is unique among regulatory proteins.
