Conservation of transmembrane helices (TMH) among MGS homologues in cyanobacteria.

<p>ClustalW sequence alignments for several MGS homologues, with TMH (as predicted by the OCTOPUS server) highlighted by line boxes. These sequences were selected from a BlastP similarity search utilizing Sll1377 as the template and refer to enzymes from (top to bottom) <i>Paulinella chromatophora</i>, <i>Nostoc</i> sp. PCC7120, <i>Anabaena variabilis</i> ATCC29413, <i>Nostoc punctiforme</i> PCC73102, <i>Cyanothece</i> sp. PCC7424, <i>Synechococcus</i> sp. PCC7002 and <i>Synechocystis</i> sp. PCC6803.
