Deamination of 4-aminopyrimidine nucleosides by extracts of rye grass (Lolium perenne).
نویسندگان
چکیده
A deaminase specific for 4-aminopyrimidine nucleosides has been found in rye grass. Lolium perenne. The pH optimum, temperature stability, Km values and specificity was determined.A new and more accurate method for following the course of deamination is reported. This method depends on the shift in maximum absorbance wavelength of the mixture containing the 4-aminopyrimidine nucleoside and its deaminated product.

متن کاملPhysicochemical and immunochemical characterization of allergenic proteins from rye-grass (Lolium perenne) pollen prepared by a rapid and efficient purification method.
Three fractions of rye-grass (Lolium perenne) pollen extract have been isolated by preparative isoelectric focusing (i.e.f.) and characterized in terms of physicochemical and immunochemical properties. The purified components were designated 'R7' and 'R14' on the basis of their positions in relation to other rye-grass pollen extract components on SDS/polyacrylamide-gel electrophoresis and their...
متن کاملNitrogen dynamics under Lolium perenne after a single application of three different sewage sludge types from the same treatment stream.
Three sludge types from the same treatment stream (undigested liquid, anaerobically digested liquid and dewatered, anaerobically digested cake) were used in a field based tub study. Amendments (4, 8, and 16 Mg dry solid (ds)ha(-1)) were incorporated into the upper 15 cm of a sandy loam soil prior to sowing with rye-grass (Lolium perenne L.). Nitrogen transformations in the soil were determined ...
متن کاملTranscriptome sequencing identifies novel persistent viruses in herbicide resistant wild-grasses
Herbicide resistance in wild grasses is widespread in the UK, with non-target site resistance (NTSR) to multiple chemistries being particularly problematic in weed control. As a complex trait, NTSR is driven by complex evolutionary pressures and the growing awareness of the role of the phytobiome in plant abiotic stress tolerance, led us to sequence the transcriptomes of herbicide resistant and...
متن کاملEffect of the soil treated with biochar on the rye-grass in laboratory experiment
The application of biochars to improve soils and to mitigate global climate change is a popular research area all over the world, although it is not a new topic. In our study, wood chips char (BC) and animal bone char (ABC) were applied. The pot experiments were conducted under laboratory conditions. 2 grams of rye-grass (Lolium perenne) were seeded into each pot. The following various soil par...
