Abstract
The primary structures of the C and D subunits of sarcosine oxidase from Corynebacterium sp. U-96 were determined by sequencing the peptide fragments derived from their enzymatic digestions. The C and D subunits were shown to be composed of 199 and 92 residues, respectively. Each amino acid sequence showed a high homology with the sequence of the corresponding subunit from Corynebacterium sp. P-1. However, there were some differences between these two species, that is, four N-terminal residues were truncated in the C subunit, but six C-terminal residues were truncated in the D subunit. The D subunit contained three cysteine residues, but no disulfide bonds are in the subunit. Overall sequences of both subunit showed no homology with any other protein in the data base.
