Abstract:
:Model experiments with two structurally different proteins (alcohol dehydrogenase and salmine) show that glycine, alanine, and tyrosine are by far more frequently involved in photochemically induced cross-link formations with DNA than is cysteine. The yields for cross-link formation of thymidine with salmine (cysteine-free) are about as high as those with alcohol dehydrogenase (athiol protein).
