  TITLE     Direct Submission
COMMENT     This phage display vector is derived by splicing a 379-bp 
            semi-synthetic major coat protein gene into filamentous phage vector
            fd-tet. The resulting phage has two major coat protein genes: the 
            wild-type gene VIII and the artificial one rVIII. The artificial 
            gene is driven by a tac promoter and is therefore inducible by IPTG;
            under fully induced conditions (1 mM IPTG) roughly 300 of the 3900 
            coat protein subunits stem from the artificial gene rVIII, the 
            remainder stemming from the wild-type gene VIII. The artificial gene
            rVIII has unique HindIII and PstI cloning sites separated by a 21-bp
            stuffer.  Replacement of the stuffer with an appropriate synthetic
            or natural DNA insert can result in display of up to 300 copies of a
            peptide encoded by the insert on the virion surface, fused to the 
            rVIII-derived coat protein subunits. This surface display requires 
            that the first 9 bp of the insert should encode the last three amino
            acids of the signal peptide, and that the reading frame of the 
            inserts coding sequence be correctly fused to the reading frame of 
            the remainder of the rVIII coding sequence downstream of the PstI 
            clonging site.
