Amino acid phylogenetic trees of DapF (A) and HMW-PBPs (B). Branches with less than 70% bootstrap support are represented in dotted line. The distribution of peptidoglycan amino acid component is also presented in (A). Streptomyces coelicolor A3(2) PBPs and their orthologs were grouped and expression patterns were assigned according to Noens et al.⁵⁵ in (B); those known to be expressed in aerial mycelium and vegetative mycelium are shown by AM and VM, respectively. Amino acid sequences were derived from the HAMAP database (MF_00197).
