Quantifying Bone Collagen Fingerprint Variation Between Species. [PDF]
Mol Ecol ResourABSTRACT Collagen is the most ubiquitous protein in the animal kingdom and one of the most abundant proteins on Earth. Despite having a relatively repetitive amino acid sequence motif that enables its triple helical structure, in type 1 collagen, that dominates skin and bone, there is enough variation for its increasing use for the biomolecular species
