Fig. 2

Analysis of CrtS protein from X. dendrorhous. Characteristic conserved secondary elements of P450 proteins are shown along the CrtS protein. Alpha helices (h) and beta strands (b) are represented as orange cylinders and blue arrows, respectively. The transmembrane region (TM) and conserved regions such as the “meander loop” and the “Cys pocket” are also highlighted. The location of the conserved motifs AGxDTT, ExxR, PER and CxG are shown along the protein. Residues involved in the interaction CrtS-CrtR according to [52] are marked with asterisks
