[Leucine aminopeptidase crystals from the bovine pancreas].

Crystals of leucinaminopeptidase from bovine pancreas were obtained. Space group (P6322), parameters of the cell a-b-132 A, c = 122 A and distribution of spot intensities on precessional X-ray patterns were in full agreement with corresponding parameters for leucinaminopeptidase crystals from bovine eye lens. A conclusion is drawn about similarity between the spatial structures of leucinaminopeptidase from bovine pancreas and eye lens.
