Dipeptides 126-135 cathepsin B Homo sapiens 84-95 8754751-10 1996 We conclude that the N-terminus of Tg, which contains its major hormonogenic site, is particularly susceptible to hydrolysis by the endopeptidase cathepsin B and that cathepsin B additionally has an important exopeptidase action that allows it to release a T4 dipeptide that is then further degraded by LDPI to release free T4. Dipeptides 260-269 cathepsin B Homo sapiens 167-178
