Resolution of pea legumin subunits by high-performance liquid chromatography. 1987

J R Bacon, and N Lambert, and M Phalp, and G W Plumb, and D J Wright

Pea legumin was dissociated into its component subunits by 6 M urea: these were subsequently fractionated by FPLC using a combination of Mono P, Mono Q, and Mono S columns. The resolution and speed of separation were greatly improved in comparison with previous fractionations. Twelve discrete fractions were obtained and analyzed by sodium dodecyl sulfate-polyacrylamide gel electrophoresis. Six "normal" legumin subunits (Mr 60,000) were identified as well as some "large" (Mr 66,000) and "small" (Mr 44,000) subunits. A few polypeptides of unknown origin were also observed. Four subunits were purified to homogeneity as adjudged by electrophoresis and HPLC and in sufficient yields to permit further studies. Anomalous electrophoretic behavior of the legumin subunits was also observed.

UI	MeSH Term	Description	Entries
D007887	Fabaceae	The large family of plants characterized by pods. Some are edible and some cause LATHYRISM or FAVISM and other forms of poisoning. Other species yield useful materials like gums from ACACIA and various LECTINS like PHYTOHEMAGGLUTININS from PHASEOLUS. Many of them harbor NITROGEN FIXATION bacteria on their roots. Many but not all species of "beans" belong to this family.
