Gene SO_1960 from Shewanella oneidensis encodes the NP_717567 protein, a putative endoribonuclease (45% seq. id. with YP_003302408). Its sequence similarity to proteins from COG0251 (putative translation initiation inhibitor from yjgF family) and very weak (e-val=0.0082) to PF01042 (endoribonuclease L-PSP) indicates that this protein may function as an endoribonuclease acting on single-stranded mRNA that inhibits protein synthesis by mRNA cleavage.
SCOP classifies 2otm in the alpha+beta class, YjgF-like superfamily, YjgF/L-PSP family.
According to DALI, 2otm shows structural similarity to a protein with unknown function PDB:3d01 (Z=24), the TDCF protein PDB:2uyn (Z=13), and to the YjgF proteins PDB:1qu9 (Z=13) and PDB:1pf5 (Z=10).
