Summary: Four enzymes, namely leucine aminopeptidase (LAP), membrane alanyl aminopeptidase (MAA), aspartyl aminopeptidase (DAP) and propyl aminopeptidase (PA) are involved in releasing amino acids from protein substrates in malaria cells. Because of their central role in protein turnover and synthesis they each represent a target at which novel anti-malaria drugs could be directed. However, before embarking on a drug discovery program, basic information on their biochemistry, structure, expression and relative importance in malaria cell metabolism is needed. This project employs recent advances in 3-dimensional modelling, enzyme kinetics, site-directed mutagenesis and gene knockdown/over-expression to enlighten us about these essential enzymes.
