RESUMO
Lysyl hydroxylase (peptidyllysine, 2-oxoglutarate: oxygen 5-oxidoreductase, EC 1.14.11.4) has a high affinity for columns of concanavalin A-agarose, which was markedly reduced in the presence of alpha-methyl-D-mannoside, suggesting that the enzyme is a glycoprotein. Once bound, the enzyme could not be eluted with the glycoside alone, whereas an effective elution was achieved by a combination of alpha-methyl-D-mannoside and ethylene glycol. The data thus suggest that hydrophobic interaction stabilized the complex of the enzyme with the column. This information was applied to obtain a lysyl hydroxylase purification of about 3000-fold with a recovery of more than 10% from extract of chick embryos by relatively simple steps.
