Presence of Tic62-NAD(P)-related proteins in cyanobacteria, algae, land plants and green sulphur bacteria. Tic62 is a bimodular protein (Nt and Ct modules for NAD(P) and FNR binding, respectively) with a transient transit peptide (TP) for importing into chloroplasts. The presence of the modules and/or the transit peptide is indicated for the Tic62-NAD(P)-related proteins. A question mark indicates that the complete genome is not available and: ^a the absence of the protein cannot be assured; ^b the existence of a transit peptide is not known. ^cProteins corresponding to group IV are only found in unicellular and filamentous diazotrophic cyanobacteria and not in others such as Gloeobacter violaceus, Prochlorococcus marinus or Synechocystis sp. PCC 6803 (see text). The accession numbers in the corresponding database (indicated in brackets) for the proteins found in this figure are the following: Arabidopsis thaliana (GenBank), NP_188519 (group I), NP_565789 (group II), NP_568098/NP_565868 (group IV, without/with transit peptide), NP_194881 (group V); Physcomitrella patens (PhyscoDB), contig 2031 (group I), contig 5715 (group II), contig1791/contig9865 (group IV, without/with transit peptide), BQ040198 (group V); Chlamydomonas reinhardtii (ChlamyDB), 193756 (group II), 118820 (group IV), 123134 (group V); Galdieria sulphuraria (The Galdieria sulphuraria Genome Project), hter25g11 (group I), A436F01 (group IV); Nostoc sp. PCC7120 (GenBank), ZP_00112007 (group III), BAB74602 (group IV); Chlorobium phaeobacteroides (GenBank), ZP_00528087 (group VI).
