“…Specifically for the bands of tropomyosin, troponin-T and others in the range 30-40 kDa, another explanation is possible: the addition of MTGase itself, since this enzyme has a chemical molecular weight of 37,863 Da (Kanaji et al, 1993), which falls within the mentioned range. On the other hand, actin was unaffected by MTGase, probably as a result of low exposure of the susceptible amino acid residues (Gln and Lys) in its globular conformation (Ramírez-Suárez et al, 2005).…”
