fluorescence and optical detection of triplet state magnetic resonance ( odmr ) spectroscopy have been employed to study the complexes formed between single-stranded polynucleotides and escherichia coli ssb gene products ( ssb ) in which tryptophans 40 , 54 , and 88 are selectively , one residue at a time , replaced by phenylalanine using site-specific oligonucleotide mutagenesis .
