Native Bovine Osteocalcin

• Cat.No.: BGLAP-286B

Specification

• Species: Bovine
• Source: Plasma
• Tag: Non
• Description: Osteocalcin, also known as Bone-Gla-Protein (BGP), is a single chain (Mr=5800) vitamin K dependent protein produced by osteoblasts and found in high concentrations in bone. Post-translational modification by a vitamin K dependent carboxylase produces three g-carboxyglutamic acid residues at positions 17, 21 and 24. The mature protein contains 49 amino acids and a single intrachain disulfide bond joining Cys23 to Cys29. The secondary structure is highly calcium dependent and contains 14% α-helix, 20% β-sheet and 67% random form in the presence of calcium, and 1% α-helix, 20% β-sheet and 79% random form in the absence of calcium.
