IDENTIFICATION OF METHIONINE N-ALPHA-ACETYLTRANSFERASE

摘要

2067757 9106636 PCTABS00005 A Methionine N.alpha.-acetyltransferase enzyme has been identified in yeast. The existence of the enzyme defines a gene for methionine N.alpha.-acetyltransferase which may be cloned and altered. Cells expressing the normal or variant forms of this enzyme are valuable tools for determining the amino acid sequence of uncharacterized proteins. Such cells are also valuable tools for expressing a recombinant protein lacking an acetyl group at its .alpha.-amino group.
