 9.B.106 The Pock Size-determining Protein (PSDP) Family

The pock size-determining protein, SpdB, is encoded on plasmid pSN22 (Kataoka et al., 1991a). It may also enhance efficiency of plasmid transfer (Kataoka et al., 1991b). It is under TraR control and has 325 aas and 4 N-terminal TMSs. Four SpdB genes (SpdB1-SpdB4) have been detected (Kataoka et al., 1994). The C-terminal hydrophilic domain is an Ala/Glu-rich domain that is similar to domains in other proteins such as TolA of E. coli (TC# 1.A.30.2.2).

This family belongs to the: Protein Kinase (PK) Superfamily.
