Fig 4. Unrooted phylogenetic tree of NB-ARC and NACHT NTPases.
The members of NACHT and NB-ARC NTPases of S. moellendorffii were aligned with NACHT NTPases of green algae, cyanobacteria and Physcomitrella patens using ClustalW v2.1 and a phylogenetic tree was constructed by employing MEGA v5.2.2. The NLRC4 NACHT was taken as representative of NACHT and APAF1 NB-ARC as NB-ARC representative. (The S_moe_* denotes NACHT NTPases and NB-ARC AP-ATPases in S. moellendorffii, C_re_* for C. reinhairdtii and C_sub_* for C. subellipsoidea where * represents any integer number.)
