OBSOLETE. Catalysis of the reaction: m+q H2O + a 6-phosphogluco-3-phosphogluco-amylopectin = m+q hydrogenphosphate + a 6-phosphogluco-3-phosphogluco-amylopectin.
A protein complex formed by the association of the guanine nucleotide exchange factor synembrin with the alpha(q) subunit of a heterotrimeric G protein.
Catalysis of the transfer of a methyl group from S-adenosylmethionine during the synthesis of quinone cofactors such as ubiquinone (coenzyme Q), menaquinone (vitamin K2), plastoquinone and phylloquinone (vitamin K1).
The chemical reactions and pathways involving the Q nucleoside precursor 7-cyano-7-deazaguanine, also known as 2-amino-4-oxo-4,7-dihydro-3H-pyrrolo[2,3-d]pyrimidine-5-carbonitrile or preQo.
The chemical reactions and pathways resulting in the formation of the Q nucleoside precursor 7-cyano-7-deazaguanine, also known as 2-amino-4-oxo-4,7-dihydro-3H-pyrrolo[2,3-d]pyrimidine-5-carbonitrile or preQo.
Binds to DNA, typically within region of the promoter and transcribed region, to promote readthrough of a transcription termination site and thus extending the length of the RNA transcript produced. Examples of antitermination factors which bind DNA include the lambda Q protein.
The aggregation, arrangement and bonding together of a set of components to form the cytochrome bc(1) complex, a transmembrane lipoprotein complex that it catalyzes the reduction of cytochrome c by accepting reducing equivalents from Coenzyme Q, by the aggregation, arrangement and bonding together of its constituents.
The aggregation, arrangement and bonding together of a set of components to form a SNARE complex, a protein complex involved in membrane fusion; a stable ternary complex consisting of a four-helix bundle, usually formed from one R-SNARE and three Q-SNAREs with an ionic layer sandwiched between hydrophobic layers.
The disaggregation of the SNARE protein complex into its constituent components. The SNARE complex is a protein complex involved in membrane fusion; a stable ternary complex consisting of a four-helix bundle, usually formed from one R-SNARE and three Q-SNAREs with an ionic layer sandwiched between hydrophobic layers.
