Collagenase and Elastase

Collagenase and elastase are two distinct classes of proteolytic enzymes that play synergistic roles in the degradation and remodeling of the extracellular matrix (ECM) [8, 11]. Collagenases, primarily members of the matrix metalloproteinase (MMP) family or bacterial enzymes, specifically cleave the triple-helical structure of native collagen, while elastases (including serine proteases like neutrophil elastase and certain MMPs) target elastin fibers [5, 14]. Together, these enzymes are critical for physiological processes such as wound healing, tissue dissociation, and embryonic development [9, 10]. However, their overactivation is a hallmark of various pathological conditions, including skin photoaging, chronic obstructive pulmonary disease (COPD), and cancer metastasis, where they facilitate tissue destruction and cellular invasion [2, 6, 12]. In the pharmaceutical and cosmetic industries, these enzymes are frequently targeted together, particularly in anti-aging formulations where natural polyphenols like EGCG or synthetic inhibitors are used to preserve skin elasticity and structural integrity [4, 13]. Conversely, purified collagenase and elastase blends are utilized therapeutically and in laboratory settings for tissue dissociation and the treatment of fibroproliferative disorders like Dupuytren's contracture [1, 8]. The term 'Collagenase/Elastase' is considered incorrect as a single target because it represents a functional grouping of two separate enzyme types rather than a single molecular entity.
