Cloned(Commentary)

Cloned (Comment) Organism
expression of wild-type and mutant AP proteins and domains at high levels in inclusion bodies Pseudomonas aeruginosa

Protein Variants

Protein Variants Comment Organism
additional information generation of a series of full-length and truncation mutants for structural and functional studies, overview. DELTAN-AP shows increased thermal sensitivity compared with the wild-type enzyme. At 42°C, protease activity decreases by 50%, and at 55°C, protease activity decreases by 90% when compared with the full-length AP in 2 mM Ca2+ Pseudomonas aeruginosa

Metals/Ions

Metals/Ions Comment Organism Structure
Ca2+ calcium-regulated alkaline protease, role of Ca2+ in enzyme folding and activation: Ca2+binding induces RTX folding, which serves to chaperone the folding of the protease domain. Subsequent association of the RTX domain with an N-terminal alpha-helix stabilizes AP, Ca2+ regulates the RTX family of virulence factors, overview Pseudomonas aeruginosa
