Ester vs Ether lipids 10.2 Eubacteria Archaea
Nucleated prokaryotes 10.2a Planktomycetes Poribacteria
n Cellulose vs Chitine 10.2b • Opisthokonts produce chitine, not cellulose Except 2 taxa via lateral gene transfer from -proteobacteria Urochordates (Matthysse et al (2004) PNAS27:986-981) Aspergillus fumigatus (Nobles et al Cellulose 11:437-448) Deuterostomes don’t produce chitine but CaCO3 and keratine in tetrapoda • Amoebas (Dictyostelium) & bikonts got cellulose synthetase from cyanobacteria • Some chlorophytes produce chitinase • Many fungi produce cellulase, no animals can (symbiosis) Cellulose (C12H20O10)n Chitine (C16H26O10N2)n Ciona Aspergillus fumigatus
Planktomycetes 10.2d • eubacteria with nuclear membranes • like eukaryotes • some species can oxidize ammonia anaerobically • they have ether lipids, like archaea • some species have genes for formaldehyde detoxification • that archaea use for methanogenesis & • archaea & eubacteria for methanotrophy • are abundant in stromatolites • fossil stromatolites date from 3.5 Ga ago • propagate by budding • probably passed its 16 genes for C1-detoxification • to archea for methane production/consumption Planctomyces
Evolution of central metabolism 10.2.1 in prokaryotes (= bacteria) 3.8 Ga 2.7 Ga i = inverse ACS = acetyl-CoA Synthase pathway PP = Pentose Phosphate cycle TCA = TriCarboxylic Acid cycle RC = Respiratory Chain Gly = Glycolysis Kooijman, Hengeveld 2005
Prokaryotic metabolic evolution 10.2.1a • Heterotrophy: • pentose phosph cycle • glycolysis • respiration chain • Phototrophy: • el. transport chain • PS I & PS II • Calvin cycle • Chemolithotrophy • acetyl-CoA pathway • inverse TCA cycle • inverse glycolysis
