Human serum albumin complexed with myristate and aspirin
Contents |
Overview
Human serum albumin (HSA) is the most abundant plasma protein in the human, body with a plasma concentration of 0.6mM. HSA plays an important role in, drug transport and metabolism. Enzymatic activity of HSA on different, substrates or drugs has been studied and documented. The structural, mechanism of this activity, however, is unknown. In this study, we have, determined the crystal structures of HSA-myristate in a complex of aspirin, and of salicylic acid, respectively. The crystal structure of, HSA-myristate-aspirin illustrates that aspirin transfers acetyl group to, Lys199 and is hydrolyzed into salicylic acid by HSA. The hydrolysis, product, salicylic acid, remains bound to HSA at a similar location, but, it shows a very different orientation when compared with the salicylic, acid in the HSA-myristate-salicylic acid ternary complex. These results, not only provide the structural evidence of esterase activity of HSA, and, demonstrate the conformational plasticity of HSA on drug binding, but also, may provide structural information for the modulation of HSA-drug, interaction by computational approach based on HSA-drug structure.
