| Abstract: | The aralkyl acyl-CoA:amino-acid N-acyl-transferase was previously purified to homogeneity from bovine liver mitochondria. The N-terminal amino-acid sequence and sequences obtained by cyanogen bromide cleavage of the enzyme were used to design oligonucleotide probes that were used to screen a bovine liver cDNA library. Several clones were isolated and sequenced, and the sequence is given. The cDNA contains 126 bases of 5′-untranslated region and 188 bp of 3′ untranslated region. The cDNA codes for an enzyme containing 295 amino-acid residues. The sequence gives a molecular weight for the enzyme of 39,229, which is larger than previously estimated. The amino-acid composition of the enzyme, based on this sequence, is in agreement with the previously obtained amino-acid analysis on the purified kidney enzyme. © 1997 John Wiley & Sons, Inc. |
