FIG. 1.

(A) Amino acid sequence comparison of the three C. crescentus genes containing one CSD with E. coli cspA (GenBank no. AAB18533). (B) Amino acid sequence comparison of the proposed new annotation of cspD from C. crescentus (Cc) with other predicted α-Proteobacteria peptides showing two CSDs. Above the sequences are indicated the two RNA-binding motifs (RNP1 and RNP2). Residues shaded in black indicate conserved residues present in at least 90% of the proteins; those shaded in dark gray are present in at least 60% of the proteins. The GenBank no. and abbreviations are as follows: Agrobacterium tumefaciens (At; AAK87573), Sinorhizobium meliloti (Sm; CAC46297), Brucella melitensis (Bm; AAL51912), Mesorhizobium loti (Ml; BAB47810), Rhodopseudomonas palustris (Rp; ZP_00012063), Magnetospirillum magnetotacticum (Mm; ZP_00049605), Rhodobacter sphaeroides (Rs; ZP_00006193), Novosphingobium aromaticivorans (Na; ZP_00093526), and Rhodospirillum rubrum (Rr; ZP_00013462).
