Using the DNA duplex containing an AP site (5'-TCC AGX GCA AC-3'/3'-AGG TCN CGT TG-5', X = AP site, N = A, T, C, or G), we have found that 2-amino-4-hydroxypteridine (pterin) selectively binds to guanine (G), and that the enhanced binding affinity for G is obtained by its methylated derivative 2-amino-6,7-dimethyl-4-hydroxypteridine (diMe pteridine). Similarly, among the cytosine (C)-selective ...
Physarum polycephalum, an acellular slime mould, serves as a model system to study cell-cycle-dependent events since nuclear division is naturally synchronous. This organism was shown to release isoxanthopterin which is structurally related to tetrahydrobiopterin, a cofactor of aromatic amino acid hydroxylases and of nitric oxide synthases (NOSs) (EC 1.14.13.39). Here, we studied Physarum pteri...
LUORESCENT pteridine compounds have been identified in Drosophila by HADORN and MITCHELL ( 195 1 ) , and FORREST and MITCHELL (1 954a,b, 1955). Variation in the accumulation of the various pteridines from species to species in the genus Drosophila has been discussed by RASMUSSEN and SCOSSIROLLI (1954), RASMUSSEN (1954, 1955), HUBBY and THROCKMORTON ( 1960), and THROCKMORTON ( 1962). HUBBY and T...
Leishmania is a protozoan parasite responsible for significant morbidity and mortality worldwide. Few parasites have been subjected to proteomic analysis to date, but a genome sequencing project for Leishmania major is currently underway, making these studies possible. Here we present a high resolution proteome for L. major comprising almost 3700 spots, making it the most complete two-dimension...
