Prokaryotic contextual genome evidence for the functional prediction of AT1G78620 as putative phytyl-phosphate kinase. (A) Typical examples of physical clustering between the AT1G78620 homologs in bacteria and Archaea (COG1836) and phytol kinase (PK) or other genes of polyprenyl metabolism. (B) Examples of domain fusions between the predicted phytyl-phosphate kinase and phytol kinase. Arrows of the same color represent homologous genes; genes not involved in conserved clustering are shown in gray. COG1836, predicted phytyl-phosphate kinase; DS, putative dehydrosqualene/phytoene desaturase; IPK, isopentenyl phosphate kinase; PPS, polyprenyl pyrophosphate synthetase, AT, Arabidopsis; C. tepid, Chlorobium tepidum TLS; E. lenta, Eggerthella lenta; Nostoc, Nostoc sp. 7120; P. arsen, Pyrobaculum arsenaticum.
