Metabolite of Species Details
Escherichia coli (NCBI:562) See: PubMed
Roles Classification
Chemical Role(s): Bronsted acid
A molecular entity capable of donating a hydron to an acceptor (Bronsted base).
(via hydracid )
Biological Role(s): Escherichia coli metabolite
Any bacterial metabolite produced during a metabolic reaction in Escherichia coli.
signalling molecule
A molecular messenger in which the molecule is specifically involved in transmitting information between cells. Such molecules are released from the cell sending the signal, cross over the gap between cells by diffusion, and interact with specific receptors in another cell, triggering a response in that cell by activating a series of enzyme controlled reactions which lead to changes inside the cell.
toxin
Poisonous substance produced by a biological organism such as a microbe, animal or plant.
metabolite
Any intermediate or product resulting from metabolism. The term 'metabolite' subsumes the classes commonly known as primary and secondary metabolites.
genotoxin
A role played by a chemical compound to induce direct or indirect DNA damage. Such damage can potentially lead to the formation of a malignant tumour, but DNA damage does not lead inevitably to the creation of cancerous cells.
Application(s): vasodilator agent
A drug used to cause dilation of the blood vessels.
