Further characterization and amino acid sequence of m-type thioredoxins from spinach chloroplasts.
The complete primary structure of m-type thioredoxin from spinach chloroplasts has been sequenced by conventional sequencing including fragmentation, Edman degradation and carboxypeptidase digestion. As already reported [Tsugita, A., Maeda, K. & Schürmann, P. (1983) Biochem. Biophys. Res. Commun. 115, 1-7] these thioredoxins contain the same active-site sequence as thioredoxins from other sources. Based on the amino acid sequence thioredoxin mc contains 103 residues, has a relative molecular mass of 11425 and a molar absorption coefficient at 280 nm of 19 300 M-1 cm-1. The spinach thioredoxin mc has an overall homology of 44% with the thioredoxin from Escherichia coli mainly due to differences in the N-terminal and C-terminal regions.
