   common Fe-S cluster and SAM binding sites are embedded into complete or incomplete beta/alpha-barrel

Families:

1. c.1.28.1: Biotin synthase [102115] (1 protein)
   regular (beta/alpha)8 barrel

2. c.1.28.2: Oxygen-independent coproporphyrinogen III oxidase HemN [102118] (1 protein)
   open beta/alpha barrel decorated with additional structures

3. c.1.28.3: MoCo biosynthesis proteins [110388] (1 protein)
