Members of this protein family are radical SAM/SPASM domain proteins likely to be involved in the modification of small, Cys-rich peptides. Members of the family of proposed target sequences, TIGR04341, average 75 amino acids in length and average six instances of the motif ACGX, where X is A, S, or T.
