The chemical reactions and pathways resulting in the breakdown of cyanogenic glycosides, any glycoside containing a cyano group that is released as hydrocyanic acid on acid hydrolysis; such compounds occur in the kernels of various fruits.

The chemical reactions and pathways resulting in the breakdown of keratan sulfate, a glycosaminoglycan with repeat units consisting of beta-1,4-linked D-galactopyranosyl-beta-(1,4)-N-acetyl-D-glucosamine 6-sulfate and with variable amounts of fucose, sialic acid and mannose units; keratan sulfate chains are covalently linked by a glycosidic attachment through the trisaccharide galactosyl-galactosyl-xylose to peptidyl-threonine or serine residues.

Any process that stops, prevents or reduces the frequency, rate or extent of histone H3-K4 acetylation.

Any process that modulates the frequency, rate or extent of histone H3-K4 acetylation.

The removal of one or more phosphate groups from thiamine diphosphate, a derivative of thiamine (vitamin B1) which acts as a coenzyme in a range of processes including the Krebs cycle.

Any process mediated by a microRNA (miRNA) that activates or increases the frequency, rate or extent of transcription from an RNA polymerase II promoter.

Any process mediated by a microRNA (miRNA) that modulates the frequency, rate or extent of transcription from an RNA polymerase II promoter.

Any process mediated by a microRNA (miRNA) that stops, prevents or reduces the frequency, rate or extent of transcription from an RNA polymerase II promoter.

Any process that activates or increases the frequency, rate or extent of histone H3-K4 acetylation.

The chemical reactions and pathways resulting in the breakdown of any of the forms of vitamin K, quinone-derived vitamins which are involved in the synthesis of blood-clotting factors in mammals.

The chemical reactions and pathways involving any of the forms of vitamin K, quinone-derived vitamins which are involved in the synthesis of blood-clotting factors in mammals. Vitamin K substances share a methylated naphthoquinone ring structure and vary in the aliphatic side chains attached to the molecule.

The chemical reactions and pathways resulting in the breakdown of phylloquinone, vitamin K1, a quinone-derived compound synthesized by green plants.

The chemical reactions and pathways involving phylloquinone, a quinone-derived compound synthesized by green plants. Phylloquinone has vitamin K activity and is known as vitamin K1.
