 Sequence Alignment of Arabidopsis PAM68 and Its Homologs from Other Species.

The sequence of the PAM68 protein was compared with related sequences from R. communis, Vitis vinifera, Populus trichocarpa, Zea mays, Oryza sativa, Physcomitrella patens subsp patens, C. reinhardtii, Synechocystis sp PCC 6803 and Synechococcus sp PCC 7002, and the Arabidopsis homolog At5g52780. The sequences were aligned using ClustalW and BoxShade (see Methods). Transit peptide sequences predicted by ChloroP are shown in lowercase letters. The two TM domains (TM1 and TM2) of each protein predicted by TMHMM (see Methods) are highlighted in bold; residues comprising the acidic domains are indicated by asterisks. Identical and closely related amino acids that are conserved in at least 30% of the aligned sequences are highlighted by black and gray shading, respectively.
