Iron-Sulfur (Fe/S) Protein Biogenesis: Phylogenomic and Genetic Studies of A-Type Carriers
Figure 2
Phylogeny of the ATC proteins.
Left part: Bayesian tree of a sample of 58 ATC sequences representative of the ATC family diversity. Numbers at nodes represent posterior probabilities. The scale bar represents the average number of substitutions per site. Right part: for each bacterial homolog, the genomic organization of regions surrounding ATC coding genes (ATC, COG0316S, red boxes) is shown. Numbers in boxes correspond to COG (Cluster of Othologous Groups) numbers. Colored boxes represent genes coding for components of the ISC system [HscB (COG1076O, pink boxes); HscA (COG0443O, purple boxes); Fdx (COG0633C, blue boxes); IscU (COG0822C, light blue boxes); IscS (COG1104E, yellow boxes) and IscR (COG1959K, light green boxes)], the SUF system [SufB/D (COG0719O, dark yellow boxes); SufS (COG0520E, dark green); SufC (COG0396O, orange boxes) and SufE (COG2166R, dark blue boxes)] or the NIF sytem [NifW (dark grey), NifU (COG0694O, light orange), NifS (COG1104E, yellow boxes)].
