The previously published structure of the glutaredoxin from calf thymus [Klintrot et al., (1984) Eur. J. Biochem. 144, 417-423] was reinvestigated by tandem mass spectrometry and found to have an N-terminal Ac-Ala-Gln-Ala-... sequence and an additional four amino acids inserted between positions 67 and 68.
