    Protein Summary

    Npun_F2943 gene from Nostoc punctiforme pcc 73102 encodes the YP_001866417 protein from the helix-turn-helix group (PF01381).

    3cec structure belongs to the all alpha class, lambda repressor-like DNA-binding domains superfamily from SCOP. According to DALI, this putative antidote protein of plasmid maintenance system is structurally similar to the transcriptional regulator YBAQ PDB:2eby (Z=15), the bacterial antitoxin Higa From E.coli (PDB:2icp; Z=13), the CLP gene regulator PDB:3f51 (Z=9), the DNA-binding domain of the P22 C2 repressor (PDB:1adr; Z=8), and the amino-terminal domain of phage 434 repressor (PDB:1r69; Z=8).
