Any process that decreases the rate, frequency or extent of high-density lipoprotein particle clearance. High-density lipoprotein particle clearance is the process in which a high-density lipoprotein particle is removed from the blood via receptor-mediated endocytosis and its constituent parts degraded.

Catalysis of the reaction: aminohydroquinone + 2 e- + 2 H+ + 1/2 O2 = 1,2,4-benzenetriol + NH3.

The process leading to the attainment of the full functional capacity of endothelin by conversion of Big-endothelin substrate into mature endothelin.

Any process involved in the maintenance of an internal steady state of ubiquitin monomers and free ubiquitin chains at the level of the cell by recycling ubiquitin from proteasome-bound ubiquitinated intermediates.

The process of creating free ubiquitin chains, compounds composed of a large number of ubiquitin monomers. These chains are not conjugated to a protein.

The process in which free ubiquitin chains, compounds composed of a large number of ubiquitin monomers, are broken down.

Catalysis of the reaction: pryrole-2-carboxylate + H+ = pyrrole + CO2.

Catalysis of the reaction: cis-2-methyl-5-isopropylhexa-2,5-dienoic acid + ATP + CoASH = cis-2-methyl-5-isopropylhexa-2,5-dienoyl-CoA + AMP + PPi.

Catalysis of the joining of an acid and a thiol via a carbon-sulfur bond, with the concomitant hydrolysis of the diphosphate bond in ATP or a similar triphosphate.

Catalysis of the reaction: substrate + ATP + CoASH = AMP + diphosphate + substrate-CoA.

Any process that modulates the rate, frequency, or extent of SMAD protein complex assembly. SMAD protein complex assembly is the aggregation, arrangement and bonding together of a set of components to form a protein complex that contains SMAD proteins.

Any process that modulates the frequency, rate or extent of protein complex assembly.

Catalysis of the reaction: 5-oxo-4,5-dihydropyrrole-2-carboxylate + 2 H2O = 2-oxoglutarate + NH3.

Any process that decreases the rate, frequency, or extent of SMAD protein complex assembly. SMAD protein complex assembly is the aggregation, arrangement and bonding together of a set of components to form a protein complex that contains SMAD proteins.

Any process that stops, prevents, or reduces the frequency, rate or extent of protein complex assembly.

Any process that decreases the rate, frequency, or extent of the series of molecular signals generated as a consequence of a transmembrane receptor serine/threonine kinase binding to its physiological ligand.

The chemical reactions and pathways involving L-lyxose, the L-enantiomer of aldopentose lyxo-pentose, the C-2 epimer of xylose.

The chemical reactions and pathways resulting in the breakdown of fructose that occurs in the absence of oxygen.

The chemical reactions and pathways involving nitrotoluene, any methylbenzene molecule with NO2 group(s) attached.
