Abstract: The present invention provides a synthetic gene control region which comprises a gene regulatory sequence comprising a binding site for a gene regulatory protein of a yeast strain, and a promoter from filamentous fungal strain located downstream of the gene regulatory sequence; wherein the promoter can be recognized by the general transcription factors and RNA polymerase of the yeast strain; wherein the gene regulatory sequence is capable of regulating transcription initiated by the filamentous fungal promoter in the yeast strain.

Abstract: The present invention features antigen binding protein that bind an ORF0657n target region (SEQ ID NO: 1). ORF0657n is an S. aureus protein. ORF0657n target regions are provided by the mAb 1G3.BD4, mAb 2H2.BE11, mAb 13C7.BC1, and mAb 13G11.BF3 binding sites. In a lethal model challenge, mAb 2H2.BE11 and mAb 13C7.BC1 provided for increased survival against S. aureus infection. There was also protection demonstrated in an ex vivo model with either the IgG1 or the IgG2b form of mAb 2H2; and in a passive immunization murine indwelling catheter model using mAb 2H2.BE11.

Abstract: The present invention features polypeptides comprising an amino acid sequence structurally related to SEQ ID NO: 1, uses of such polypeptides, and expression systems for producing such polypeptides. SEQ ID NO: 1 is a truncated derivative of a full length S. aureus polypeptide. The full-length polypeptide is referred to herein as full-length “ORF0657n”. Polypeptides containing the amino acid sequence of SEQ ID NO: 1 were found to produce a protective immune response against S. aureus.
