We expressed recombinant human methionine aminopeptidase type 1 (MAP or MetAP) in a map1 null yeast strain to determine the extent of functional complementation between the two proteins. The human MetAP1 protein fully rescued the slow growth phenotype associated with deletion of yeast MetAP1, suggesting that the yeast and human MetAP1 proteins may have similar roles in vivo. Expression of human MetAP1 in yeast has significance in understanding the function of the human protein, studying its in vivo substrate specificity, and developing specific anti-fungal drugs to target yeast MetAP1.

More about this publication?
  • Protein & Peptide Letters publishes short papers in all important aspects of protein and peptide research, including structural studies, recombinant expression, function, synthesis, enzymology, immunology, molecular modeling, drug design etc. Manuscripts must have a significant element of novelty, timeliness and urgency that merit rapid publication. Reports of crystallisation, and preliminary structure determinations of biologically important proteins are acceptable. Purely theoretical papers are also acceptable provided they provide new insight into the principles of protein/peptide structure and function.
