K318 (= K193) mutation to A: Decreases enzymatic activity by 50%.; mutation to E: Completely abolishes enzymatic activity.
D341 (= D216) mutation to G: Decreases enzymatic activity by 80%.; mutation to N: Decreases enzymatic activity by 85%. Completely abolishes enzymatic activity, does not elicit cytoskeletal rearrangements, and does not suppress IL-8 production after TNF-alpha stimulation; when associated with N-345.
D345 (= D220) mutation to N: Decreases enzymatic activity by 55%. Completely abolishes enzymatic activity, does not elicit cytoskeletal rearrangements, and does not suppress IL-8 production after TNF-alpha stimulation; when associated with N-341.
