We have detected a protein kinase which phosphorylates bone phosphoproteins (BPPs) in the detergent extract of the membranous fractions in the periosteal bone strips of 12-day-embryonic-chick tibia. This enzyme, tentatively named BPP kinase, has a catalytic subunit of Mr approximately 39,000, utilizes GTP as well as ATP as a phospho-group donor, is inhibited by 2,3-bisphosphoglycerate and heparin, and is therefore similar to casein kinase II. The enzyme can phosphorylate dephosphorylated proteins such as casein, phosvitin and chicken BPPs, but the last-named are preferred substrates. The in vitro-phosphorylation-assay products of this enzyme in the extract were indistinguishable on an SDS/polyacrylamide gel from the major [32P]phosphoproteins metabolically labelled in the embryonic-chick bone tissue. The regulatory mechanisms of the phosphorylation process of BPPs by BPP kinase as well as the potential role of this enzyme in mineralization are discussed.

The degree of hydroxylation of the lysine residue located in both α1- and α2-chains of collagen in the N-terminal, non-helical telopeptide region of the molecule has been determined in collagen from various sources after isolation of the peptides (α1- and α2-CB1) that contain the lysine residue in question and are obtained by cyanogen bromide cleavage of collagen α1- and α2-chains respectively. As with collagen from chick tibia, bone collagens from rat tibia and femur and embryonic chick frontal bone, have a high degree of hydroxylation (approx. 50% or more) of the lysine residue in both α1- and α2-CB1 peptides. This is in contrast with the lack of hydroxylation of this residue in both α1- and α2-chains of all skin collagens so far examined. The presence of hydroxylysine in α1- and α2-CB1 peptides from tendon collagen is also indicated. In rat tail tendon collagen the amount of hydroxylation is only slight but in the much less soluble tendon collagen from embryonic chick leg tendons, approximately one-third of the lysine is hydroxylated.
