In order to mimic this repair process of apoenzyme, we synthesized two model compounds, in which tryptophan and/or tyrosine was covalently linked to cyclobutane thymine dimer, and measured the splitting quantum yield of dimer under 295 nm light. By investigating the photosensitized splitting properties of the dimer, some new insights into the intramolecular electron-transfer process were gained.

CML is cytogenetically marked by the philadelphia chromosome, which originates from a reciprocal translocation between chromosome 9 and 22 and is molecularly marked a chimeric bcr-abl gene, resulting from juxta-positive of the abl proto-oncogene on chromosome 9 with the bcr gene, which is normally located on chromosome 22. The chimeric bcr-abl gene expression an 8. 5kb hybrid mRNA transcript giving rise to a 210-KD fusion protein (P210〓) with increased tyrosine kinase activity. P210〓 plays a key role in the pathogenesis of CML.
