Figure 6. Analysis of RNB amino acid sequence. (a) Schematic representation of the domains found in prokaryotic exoribonuclease II: CSD, cold shock domain; RNB, conserved central region of about 400 amino acid residues that contains four sequence motifs (I–IV); S1, RNA-binding domain. (b) Multiple amino acid sequence alignment (CLUSTAL X^43) of the residues comprising the motifs I to IV of the RNB domain (upper part) and the N-terminal part of the RNB domain (*) containing a new conserved region (lower part). The consensus sequence is represented bellow the alignment. Bacterial genus and species are abbreviated as follows: Esco, Escherichia coli K12 (acession number: NP_415802.1); Vich, Vibrio cholerae O395 (ZP_00754758.1); Vivu, Vibrio vulnificus CMCP6 (NP_762129.1); Shfl, Shigella flexneri 2a str. 2457T (NP_836978.1); Saty, Salmonella typhimurium LT2 (AAL20620.1); Yepe, Yersinia pestis biovar Medievalis str. 91001 (AAS62250.1); Erca, Erwinia carotovora subsp. atroseptica SCRI1043 (CAG74865.1); Phlu, Photorhabdus luminescens subsp. laumondii TTO1 (NP_929629.1); Hain, Haemophilus influenzae Rd KW20 (NP_439875.1); Haso, Haemophilus somnus 2336 (ZP_00133292.2); Pamu, Pasteurella multocida subsp. multocida str. Pm70 (AAK02265.1); Acpl, Actinobacillus pleuropneumoniae serovar 1 str. 4074 (ZP_00134345.1). Numbers of intervening amino acids are given in brackets. (c) Secondary structure prediction of the N-terminal part (residues from 85 to 156) of the RNB domain of E.coli RNase II. β-Sheet elements are illustrated as arrows. The secondary structure prediction was made using 3D-PSSM program, Folding Recognition Server. Figure 6. Analysis of RNB amino acid sequence.
