Catalysis of the release of ammonia or one of its derivatives, with the formation of a double bond or ring. Enzymes with this activity may catalyze the actual elimination of the ammonia, amine or amide, e.g. CH-CH(-NH-R) = C=CH- + NH2-R. Others, however, catalyze elimination of another component, e.g. water, which is followed by spontaneous reactions that lead to breakage of the C-N bond, e.g. L-serine ammonia-lyase (EC:4.3.1.17), so that the overall reaction is C(-OH)-CH(-NH2) = CH2-CO- + NH3, i.e. an elimination with rearrangement. The sub-subclasses of EC:4.3 are the ammonia-lyases (EC:4.3.1), lyases acting on amides, amidines, etc. (EC:4.3.2), the amine-lyases (EC:4.3.3), and other carbon-nitrogen lyases (EC:4.3.99).

The assembly and organization of the sperm flagellar axoneme, the bundle of microtubules and associated proteins that forms the core of the eukaryotic sperm flagellum, and is responsible for movement.

Catalysis of the release of ammonia by the cleavage of a carbon-nitrogen bond or the reverse reaction with ammonia as a substrate.

Any ubiquitin ligase complex in which the catalytic core consists of a member of the cullin family and a RING domain protein; the core is associated with one or more additional proteins that confer substrate specificity.

Catalysis of the release of amides or amidines by the cleavage of a carbon-nitrogen bond or the reverse reaction with an amide or amidine as a substrate.

The process whereby a relatively unspecialized cell acquires specialized features of a muscle cell.

Catalysis of the release of amides by the cleavage of a carbon-nitrogen bond or the reverse reaction with an amine as a substrate.

The breakdown into simpler components of glycerol, 1,2,3-propanetriol, a sweet, hygroscopic, viscous liquid, widely distributed in nature as a constituent of many lipids.

Catalysis of the reaction: 3-alpha(S)-strictosidine = tryptamine + secologanin.

Any process that modulates the frequency, rate or extent of melanocyte differentiation.

Catalysis of the elimination of H2S or substituted H2S.
