lysyl

- l. hydroxylase an enzyme that acts on specific l. residues in certain proteins ( E.G., collagens) with α-ketoglutarate and O2 to produce δ-hydroxylysyl residues, succinate, and CO2; this enzyme, which requires Fe2+ and ascorbate, is deficient in Ehlers-Danlos syndrome type VI. SYN: l. 2-oxoglutarate dioxygenase.
- l. oxidase an enzyme, which requires Cu2+ and O2, that oxidizes certain l. residues in collagen to allysyl residues and hydroxylysyl residues to hydroxyallysyl residues; this is a required step for the cross-linking (via aldol condensations and Amadori rearrangements) of collagen strands; a lower activity of this enzyme is associated with occipital horn syndrome.
- l. 2-oxoglutarate dioxygenase SYN: l. hydroxylase.
