WebThe propeptide lacks a cysteine switch. It is proposed to be a type II membrane protein having a transmembrane domain at the N-terminal of the propeptide, but the enzyme is released from the cell as the membrane-anchored propeptide cleaved by proprotein convertase [29]. WebMMP-23, also called cysteine array MMP, is mainly expressed in reproductive tissues. 32 The enzyme lacks the cysteine switch motif in the prodomain. It also lacks the hemopexin domain; instead, it has a cysteine-rich domain followed by an immunoglobulin-like domain. WebThe catalytic domain conforms to the metzincin clan of metallopeptidases and contains a double calcium site, which acts as a calcium switch for activity. The pro-segment traverses the active-site cleft in the opposite direction to the substrate, which precludes its cleavage. how do i allow pop ups on my ipad
