Mutations induced in Amoeba proteus by the carcinogen N-methyl-N-nitrosourethane.
Mutations have been induced in single amoebae by treatment with the powerful mutagen, iV-methyl-iV-nitrosourethane. Three mutants, which differ visibly from the parent strain to the extent that individual amoebae are recognizable and change of characteristics from normal to mutant or mutant to normal can be followed in single cells, are described. These mutant strains have been cultured in the ...
متن کاملThe sulphydryl groups of sickle-cell haemoglobin.
particularpH owing to the screening ofthe haematin iron atom from the influence of the various ionizing groups. On this basis a larger critical I would signify that a larger concentration of salt ions is required for complete screening, and hence that there is a stronger interaction between the iron and the ionizing groups in MetHb. In conclusion, although the mechanism may be different it may ...
متن کاملReactivities of the sulphydryl groups of dog hemoglobin.
Dog hemoglobin has four sulphydryl groups at positions olfl (G18) and p93 (F9), all of which are titratable with mercurials. Only two of these, however, react with non-mercurial sulphydryl reagents. Kinetic results indicate that the reacting site might be the p”” (F9). An examination of the environment of the alI1 (G18) shows that this sulphydryl must be unreactive towards non-mercurials becaus...
متن کاملInteraction of alanine with lithium. I- the alanine–Li -n (H20) n (0–2) complexes
The energy minima of systems made of an alanine molecule, a lithium cation and a various number of watermolecules have been determined with the help of quantum mechanical computations at the B3LYP DensityFunctional Theory level of computation and the standard 6-311++G (d,p) basis set. Several structures, close inenergy are found and the presence of one or two water molecules around the cation m...
