TEAP/cytochrome b domain contrast with the more malleable membrane proteins like ion channels or amino-acid transporters, which undergo large conformational changes to allow passage of relatively large metabolites. This notion of a rigid hourglass scaffold found an unexpected confirmation in the observation, revealed by structural comparisons, that an helical bundle identical to the NOX/STEAP/cytochrome b enzymes is featured by a de novo designed heme-binding protein, PS1. Apparently, nature and protein designers have ind
