Crystal structure of human TMPRSS11A S368A interacting with its own zymogen activation motif

N-acetyl-beta-D-glucosamine; 2-acetamido-2-deoxy-beta-D-glucose; 2-acetamido-2-deoxy-D-glucose; 2-acetamido-2-deoxy-glucose; N-ACETYL-D-GLUCOSAMINE

TMPRSS11A non-catalytic chain remains attached to the catalytic chain via a C175-C292 disulfide bond after zymogen cleavage activation. Most of the non-catalytic chain was removed from the crystallization experiment through proteolytic cleavage at an unknown site.

TMPRSS11A catalytic chain remains attached to the non-catalytic chain via a C175-C292 disulfide bond.

baculovirus donor vector for secreted protein production from Sf9 insect cells

1.4 M sodium/potassium phosphate pH 7.4. TMPRSS11A protein (20 mg/mL) was mixed 1:1 with precipitant (0.5 uL: 0.5 uL) using an Art Robbins Phoenix crystallization robot. Crystals were mounted with reservoir solution containing 10% ethylene glycol.
