Pumpkin (Cucurbitasp.) seed globulin III. Comparison of subunit structures among seed globulins of variousCucurbitaspecies and characterization of peptide components

摘要

VariousCucurbitaseed globulins showed patterns similar to one another on SDS-gel electrophoresis,αandβbands for unreduced globulins andγ,γ′,δandδ′bands for reduced ones. On gel electrophoresis in 6Murea, reduced globulin gave two acidic and two basic bands. These corresponded toγandγ′chains andδ1andδ2chains, respectively, identified by two-dimensional urea-SDS gel electrophoresis. The compositions of theαandβsubun
