Unusual Fragments in the Subunit Structure of Concanavalin A

PMCID: PMC389135  PMID: 5288363

Abstract

Gel electrophoresis in sodium dodecyl sulfate and gel filtration in guanidine. HCl indicate that native concanavalin A contains several molecular species. An intact subunit of molecular weight 27,000 has been purified from this mixture. In addition, three fragments of the intact subunit have been isolated and characterized. A working model of the concanavalin A molecule has been constructed based on pairings of the intact subunit and of subunits consisting of fragments.

Keywords: gel electrophoresis, molecular weights
