EOG86MDZS GO:0003824 24/102 catalytic activity molecular_function "Catalysis of a biochemical reaction at physiological temperatures. In biologically catalyzed reactions, the reactants are known as substrates, and the catalysts are naturally occurring macromolecular substances known as enzymes. Enzymes possess specific binding sites for substrates, and are usually composed wholly or largely of protein, but RNA that has catalytic activity (ribozyme) is often also regarded as enzymatic." [ISBN:0198506732] EOG86MDZS GO:0009116 24/102 nucleoside metabolic process biological_process "The chemical reactions and pathways involving a nucleoside, a nucleobase linked to either beta-D-ribofuranose (a ribonucleoside) or 2-deoxy-beta-D-ribofuranose, (a deoxyribonucleoside), e.g. adenosine, guanosine, inosine, cytidine, uridine and deoxyadenosine, deoxyguanosine, deoxycytidine and thymidine (= deoxythymidine)." [GOC:ma] EOG86MDZS GO:0046331 1/102 lateral inhibition biological_process "Signaling between cells of equivalent developmental potential that results in these cells adopting different developmental fates. An example is the suppression by cells with a particular fate of the adoption of the same fate by surrounding cells." [GOC:bf, GOC:kmv]
