am·i·dase

(am'i-dās),
An enzyme that catalyzes the hydrolysis of monocarboxylic amides to free acid plus NH3; ω-amidase acts on amides such as α-ketoglutaramic acid and α-ketosuccinamic acid.

amidase

/am·i·dase/ (am´ĭ-dās)
1. any of a group of enzymes that catalyze the cleavage of carbon–nitrogen bonds in amides.
2. an enzyme that catalyzes the cleavage of the carbon–nitrogen bond of a monocarboxylic acid amide to form a monocarboxylic acid and ammonia.

amidase

[am′i·dās]
1 an enzyme that catalyzes the formation of a monocarboxylic acid and ammonia by hydrolytic cleavage of the C─N bond of a monocarboxylic acid amide.
2 a term used in the recommended and trivial names of some hydrolases acting on amides, particularly those acting on linear amides.

amidase

(am′ĭ-dās″) [ amide + -ase]
An enzyme that catalyzes the hydrolysis of amides; a deamidizing enzyme.
