Lysyl hydroxylase is a membrane-bound homodimeric protein localized to the cisternae of the endoplasmic reticulum. The enzyme (cofactors iron and ascorbate) catalyzes the hydroxylation of lysyl residues in collagen-like peptides. The resultant hydroxylysyl groups are attachment sites for carbohydrates in collagen and thus are critical for the stability of intermolecular crosslinks. Some patients with Ehlers-Danlos syndrome type VI have deficiencies in lysyl hydroxylase activity. [provided by RefSeq, Jul 2008] (from

The expression of prolyl 4-hydroxylase 1 (P4H1), lysyl hydroxylase 3 (LH3), and protein disulfide isomerase (PDI) was frequently observed on FRCs and FDCs in the germinal center (GC), except for the mantle zone.
Post-translational hydroxylation of lysine was found in a consensus sequence (XKG) known to be the site of modification in other proteins such as collagen, and was therefore presumed to result from the activity of the CHO homolog of the lysyl hydroxylase complex.

Carotenoidless light-harvesting complexes (DPA-complexes) LH1-RC and LH2 were isolated from the purple sulfur bacterium Ectothiorhodospira haloalkaliphila in which carotenoid biosynthesis was suppressed with diphenylamine (DPA).

We identified Relm-α as one important player in the pathway from IL-4Rα signaling in macrophages to the induction of lysyl hydroxylase 2 (LH2), an enzyme that directs persistent pro-fibrotic collagen cross-links, in fibroblasts.

Ca(v) beta(4) protein was detected throughout the developing cerebellum, particularly in the molecular layer, and in contrast to the other subunits, Ca(v) beta(4) was mainly detected in the molecular layer and the hilus of the hippocampus.

Data show that homozygous and compound heterozygous changes found in PLOD1 and SLC2A10 may confer autosomal recessive effects, and three MYH11, ACTA2 and COL3A1 heterozygous variants were considered as putative pathogenic gene alterations.
