Determination of partial amino acid sequence of lipoate acetyltransferase of rat pyruvate dehydrogenase complex

Protein Seq Data Anal. 1989 Dec;2(6):441-4.

Abstract

The partial amino acid sequence of rat lipoate acetyltransferase was determined using the intact protein and the peptides derived from a digest with Achromobacter protease I. The results showed the amino-terminal sequence of the mature enzyme to be (N) Ser-Leu-Pro-Pro-His-Gln-Lys-Val-Pro-Leu-Pro-Ser- Leu-Ser-Pro-Thr-Met-Gln-Ala-Gly-Thr-Ile-Ala-Arg-Trp-Glu-Lys. In addition, the sequences of two possible lipoyl-binding sites in the subunit, which are very similar to each other, were established.
