The formation of a mixture of the two possible enantiomers from the D- or L-enantiomer of a chiral amino acid.

Catalysis of the reaction: (protein)-L-serine = (protein)-D-serine.

The covalent linkage of heme to peroxidase via dihydroxyheme-L-aspartyl ester-L-glutamyl ester-L-methionine sulfonium.

The covalent linkage of heme to peroxidase.

The covalent linkage of heme to peroxidase via dihydroxyheme-L-aspartyl ester-L-glutamyl ester.

The methylation of glutamine to form 2-methyl-L-glutamine.

Any process that activates or increases the frequency, rate or extent of natural killer cell degranulation.

Any process that modulates the frequency, rate, or extent of natural killer cell degranulation.

Any process that stops, prevents, or reduces the rate of natural killer cell degranulation.

The regulated exocytosis of secretory granules containing preformed mediators such as perforin and granzymes by a natural killer cell.

Catalysis of the reaction: N(4)-acetyl-L-2,4-diaminobutyrate = ectoine + H(2)O.

Catalysis of the reaction: 1,5-anhydro-D-fructose = 1,5-anhydro-4-deoxy-D-glycero-hex-3-en-2-ulose + H2O.

Any process that activates or increases the frequency, rate or extent of cytotoxic T cell degranulation.

Any process that modulates the frequency, rate, or extent of cytotoxic T cell degranulation.

Catalysis of the reactions: 1,5-anhydro-D-fructose = 2-hydroxy-2-(hydroxymethyl)-2H-pyran-3(6H)-one + H2O; (1a) 1,5-anhydro-D-fructose = 1,5-anhydro-4-deoxy-D-glycero-hex-3-en-2-ulose + H2O and (1b) 1,5-anhydro-4-deoxy-D-glycero-hex-3-en-2-ulose = 2-hydroxy-2-(hydroxymethyl)-2H-pyran-3(6H)-one.

Any process that stops, prevents, or reduces the rate of cytotoxic T cell degranulation.

Catalysis of the reaction: (1->4)-beta-D-glucuronan = an oligosaccharide with 4-deoxy-beta-D-gluc-4-enuronosyl end + (1->4)-beta-D-glucuronan. This reaction is the eliminative cleavage of (1->4)-beta-D-glucuronans to give oligosaccharides with 4-deoxy-beta-D-gluc-4-enuronosyl groups at their non-reducing ends. Complete degradation of glucuronans results in the formation of tetrasaccharides.

The regulated exocytosis of secretory granules containing preformed mediators such as perforin and granzymes by a cytotoxic T cell.
