^*The full-length E. coli (Ec) lipid A biosynthesis proteins were compared to their predicted A. thaliana (At) counterparts, as currently annotated in The Arabidopsis Information Resource (TAIR) database. The number of amino acid residues for each protein is indicated.

^†Sequence similarity is shown as identities/positives/length of aligned segments (gaps not indicated). Pairwise BLASTp alignment (40) was used to determine the E values.

^‡These sequences are supported by the identification of full-length mRNA transcripts and EST records.

^§These protein sequences are deduced from the genomic DNA sequences without documentation of full-length mRNA transcripts or EST records.

^¶These protein sequences are deduced from the genomic DNA sequences together with some EST records.
