title: [Isolation of multiple forms of metleghemoglobin reductase and leghemoglobin components from lupin nodules].
abstract: Method for simultaneous obtaining in homogeneous state of two main forms of metleghemoglobin reductase and main leghemoglobin components from lupine nodules was worked out. The method included steps of saturation with ammonium sulphate (40-80%), gel-filtration on Ultrogel AcA 44, isoelectric focusing and repeated isoelectric focusing. As result the forms of metleghemoglobin reductase with molecular weights 62 and 66 kDa were obtained purified 725 and 402 times respectively and obtained in homogeneous state. The total yield of activity was 37%. The form with 62 kDa molecular weight was more active.
