lH NMR characterization of two crambin species
... Crambin as isolated from the seeds of Crambe abyssinica separates on HPLC in two protein fractions. The amino acid analysis and the NMR spectra of these fractions show that these are single proteins, a Ser-22/Ile-25 and a Pro-22/Leu-25 species, occurring in an approximate ratio of 55 : 45. This find ...
