Comments "The construction costs for a PSU in AAP bacteria is much higher (Table 5), about 10-fold higher than for PRP [proteorhodopsin (PR)-based phototrophic] bacteria. The most expensive step in PSU construction is synthesis of the amino acids needed for the 31 peptides in a typical AAP bacterial PSU (Table 5). Amino acid polymerization for each peptide is the next most expensive step. Pigment synthesis is the least expensive component of PSU construction in AAP bacteria and would not increase much even if [researchers] assume that oceanic AAP bacteria have two light harvesting antenna complexes rather than the one (LH1) commonly observed in marine AAP isolates (Koblížek et al., 2003). In total, a typical PSU in AAP bacteria costs about 8.29×10^-18 kJ to construct." See notes beneath table
