Roles for the proteins in ISC biogenesis. Likely roles for the different proteins in the scheme shown in Figure 2 are indicated by a '+' sign. The letter codes refer to the blocks in Figure 2. Entries not in bold are not likely due to Occam's razor rule, although they reproduce the experimental results.
