Title: Purification of leghemoglobin from nodules of Crotalaria infected with Rhizobium
Author: Mendonca, EHM

Abstract: The leghemoglobin from nodules of Crotalaria juncea infected with Rhizobium spp. was purified to homogeneity. The protein was purified after precipitation with 40-80% (NH4)(2)SO4, and chromatography by anionic exchange and gel filtration. The leghemoglobin has a single component and showed an apparent M-r of ca. 17,300 and 23,700 determined by SDS-PAGE and gel filtration, respectively. The amino acid composition showed that asparagine/aspartic acid, glutamine/glutamic acid, alanine, lysine, serine and leucine were the main amino acids. Iron was detected only in the band corresponding to the purified protein. The N-terminal amino acid sequence for the first 19 residues showed high similarities with several other leghemoglobins from other plants. (C) 1998 Elsevier Science Ltd. All rights reserved.
