Collagen hereditary link. Collagen is one of the long, fibrous structural proteins whose functions are quite different from those of globular proteins, such as enzymes. Tough bundles of collagen called "collagen fibers" are a major component of the extracellular matrix that supports most tissues and gives cells structure from the outside, but collagen is also found inside certain cells. Collagen has great tensile strength, and is the main component of fascia, cartilage, ligaments, tendons, bone and skin. Along with elastin and soft keratin, it is responsible for skin strength and elasticity, and its degradation leads to wrinkles that accompany aging. It
Prolidase deficiency available for the cell to reuse – not least in the synthesis of new collagen. This recycling by prolidase, seen in the image above, is essential for maintaining proline-based systems in the cell, such as the collagen-rich extracellular matrix (ECM), which serves to physically support the structure of internal organs and connective tissues. Inadequate recycling due to a dysfunctional prolidase enzyme, caused by an appropriate mutation in the pertinent gene, leads to the deterioration of that support structure and therefore the connective tissue of the skin, capillaries, and the lymphatic tissue, as is the case in PD. In particular, it
