Sequence alignment of the SSB proteins from A. aeolicus (SSB Aae), E. coli (SSB Eco) and S. solfataricus (SSB Sso). The asterix (*) under residue L112 of E. coli SSB (SSB Eco) denotes the limit of the resolution of chymotryptic fragment (SSBc, residues 1–135, represented by a $ sign under W135) used to determine the structure of the native and DNA-bound SSB complex described by Raghunathan et al. (1997, 2000) (PBD codes 1kaw and 1eyg, respectively). The hash symbol (#) under residue R119 indicates the C-terminus of the tryptic fragment of S. solfataricus SSB (SSB Sso) crystallized by Kerr et al. (2003) (residues 1–119; PBD code 1o7i). The addition sign (+) under N145 of SSB Eco denotes the limit of structure determination from the autolytic fragment crystallized by Matsumoto et al. (2000) (residues 1–145; PBD code 1qvc). Notice the glutamate-rich C-terminus of SSB Aae in comparison to the glutamine-rich tail of SSB Eco. |
