This organism's cassette chromosome encodes a transpeptidase called PÂ·BÂ·PÂ·2Â·a.
The Nebraska Transposon Mutant Library consists entirely of variants of the USA300 strain of this organism. A protein from this organism tightly binds Fc (F-C) and is used to purify antibodies in "protein A chromatography." This organism is DNAse (D-N-"ace") positive, agglutinates (ag-"GLUE"-tin-ates)  brinogen ("fie"-BRIN-oh-jen) into  brin (FIB-rin) with coagulase (koh-AG-yoo-"lace"), and ferments mannitol to an acid that makes "phenol (FEE-nol) red" turn yellow. This organism's cassette chromosome encodes a transpeptidase called PÂ·BÂ·PÂ·2Â·a. Pathogenicity islands in this organism encode the antigen for toxic shock syndrome. This Gram-positive bacterium is named because it grows in golden colonies. It has recently acquired resistance to vancomycin (vank-oh-MY-sin) in addition to beta-lactam antibiotics like methicillin (meth-ih-SILL-in). For 10 points, name this superbug that causes Staph infections.
