Post-translational modificationi
The lysine tyrosylquinone cross-link (LTQ) is generated by condensation of the epsilon-amino group of a lysine with a topaquinone produced by oxidation of tyrosine.By similarity
Proteolytically cleaved by BMP1 which removes the propeptide (By similarity). Also proteolytically cleaved by ADAMTS2 and ADAMTS14, but not by ADAMTS3, at an additional cleavage site downstream of the BMP1 cleavage site (By similarity). The propeptide plays a role in directing the deposition of this enzyme to elastic fibers, via interaction with tropoelastin (By similarity). Cleavage by BMP1 to remove the propeptide does not increase enzymatic activity but increases binding to collagen (By similarity). Cleavage by ADAMTS2 produces a form with reduced collagen-binding activity (By similarity).By similarity
Sulfated at Tyr-19 and also at either Tyr-15 or Tyr-16 which enhances binding to collagen.By similarity
