The DNA sequence of a 26,677 bp fragment from the right arm of chromosome VII from Saccharomyces cerevisiae reveals 18 open reading frames (ORFs) longer than 300 bp. Eight ORFs correspond to previously characterized genes. G6620 is the 3' end of the MOL1 gene coding for a polypeptide similar to stress-inducible proteins from Fusarium; G6630 is the NAT2 gene which encodes a methionine N-acetyltransferase; G6635 is the RPL30B gene coding for the ribosomal protein L30; G6658 is RSR1 encoding a ras-related protein; G6667 is CYS4, the gene for cystathionine beta-synthase; G6670 is identical to ORF2 located close to CYS4; G6673 is PEM1/CHO2 encoding a phosphatidylethanolamine methyltransferase; G7001 is the NSR1 gene coding for a nuclear signal recognition protein. G6664 shares significant homology with the ORF YKR076w from chromosome XI. The other nine ORFs show no significant homology to any protein sequence presently available in the public data bases.

The exoproteome of Staphylococcus aureus contains enzymes and virulence factors that are important for host adaptation. We investigated the exoprotein profiles and cytokine/chemokine responses obtained in three different S. aureus-host interaction scenarios by using two-dimensional gel electrophoresis (2-DGE) and two-dimensional immunoblotting (2D-IB) combined with tandem mass spectrometry (MS/MS) and cytometric bead array techniques. The scenarios included S. aureus bacteremia, skin and soft tissue infections (SSTIs), and healthy carriage. By the 2-DGE approach, 12 exoproteins (the chaperone protein DnaK, a phosphoglycerate kinase [Pgk], the chaperone GroEL, a multisensor hybrid histidine kinase, a 3-methyl-2-oxobutanoate hydroxymethyltransferase [PanB], cysteine synthase A, an N-acetyltransferase, four isoforms of elongation factor Tu [EF-Tu], and one signature protein spot that could not be reliably identified by MS/MS) were found to be consistently present in more than 50% of the bacteremia isolates, while none of the SSTI or healthy-carrier isolates showed any of these proteins. By the 2D-IB approach, we also identified five antigens (methionine aminopeptidase [MetAPs], exotoxin 15 [Set15], a peptidoglycan hydrolase [LytM], an alkyl hydroperoxide reductase [AhpC], and a haptoglobin-binding heme uptake protein [HarA]) specific for SSTI cases. Cytokine and chemokine production varied during the course of different infection types and carriage. Monokine induced by gamma interferon (MIG) was more highly stimulated in bacteremia patients than in SSTI patients and healthy carriers, especially during the acute phase of infection. MIG could therefore be further explored as a potential biomarker of bacteremia. In conclusion, 12 exoproteins from bacteremia isolates, MIG production, and five antigenic proteins identified during SSTIs should be further investigated for potential use as diagnostic markers.
