GO:0005737 The contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures. GO:0004148 Catalysis of the reaction: N(6)-[(R)-dihydrolipoyl]-L-lysyl-[protein] + NAD+ = N(6)-[(R)-lipoyl]-L-lysyl-[protein] + NADH + H+. GO:0050660 Binding to FAD, flavin-adenine dinucleotide, the coenzyme or the prosthetic group of various flavoprotein oxidoreductase enzymes, in either the oxidized form, FAD, or the reduced form, FADH2. GO:0006103 The chemical reactions and pathways involving oxoglutarate, the dianion of 2-oxoglutaric acid. It is a key constituent of the TCA cycle and a key intermediate in amino-acid metabolism. GO:0141115 A process by which a symbiont disrupts or prematurely activates host complement so that its microbial-destroying activities fail. GO:0141117 A process by which a symbiont prevents the activation of host complement by binding a soluble complement control protein (CCP) of the host and recruiting it to the microbe surface. The normal role of CCPs is to prevent complement activation on 'self' cellular targets. When soluble CCPs are recuited to the surface of a microbe, the complement fails to activate.

PDB and ChEMBL records on this protein are shown in full. ChEMBL records from similar proteins are capped at the top 100 per protein (by pchembl) and ZINC at the top 50 (Tanimoto ≥ 0.5). ADME columns are descriptor-based screening flags, not experimental toxicity results.
