Structural requirements for eIF5A polypeptides as substrates for DHS and DOHH. Truncated polypeptides of eIF5A(Lys) and eI-F5A(Dhp) were used as substrates for DHS (Joe and Park, 1994) and DOHH (Kang et al., 2007), respectively. The relative effectiveness of truncated peptides as substrates, in comparison to the intact protein (1–154), is indicated as + + ++, + + +, ++, +, or −, where − denotes little or no substrate activity. nd Not determined
