Table 1: Genomic Normalization Description: Step by Step instructions for the removal of outlier background data and any ORF data that did not meet threshold of 2SD above background average, using original data from gpr file provided in each of the sample files. Table 2: M1 Mga+ vs Mga- Description: Step by Step instructions for the removal of outlier data as compared across all possible data points for each ORF. Data points after genomic normalization are used with resultant averages and standard deviations for each ORF computed.

Project description:GAS M49: wild type vs Δralp3 mutant
| PRJNA143401 | ENA
Project description:Two covR mutant derivatives of parental strain MGAS2221 were recovered from mice experimentally infected with MGAS2221 and shown to differ in terms of the number and concentration of secreted proteins. One of the covR mutant strains had a secretion phenotype identical to a covS mutant strain, while the other had a secretion phenotype identical to a constructed covR mutant strain. To further investigate the potential differences between the two covR mutant strains we performed expression microarray analysis. Single cultures of each of the four GAS strains tested were grown in THY broth to early exponential phase (O.D. 0.2). Two volumes of RNA protect were added, the samples incubated at room temperature for 5 minutes, and the bacteria collected through centrifugation. Total RNA was isolated via a mechaniscal disruption method, converted to cDNA, fragmented, labeled, and hybridized to our Affymetrix microarray. Estimates of gene expression were calculated using GCOS software v1.4. Data represent probes for serotype M1.

Project description:The goal of this study were to compare the transcriptoms of CcpA and CovR in group A Streptococcus. Isogenic mutant strains were created in which CcpA and CovR were inactivated alone and in combination. The transcriptomes of the four strains (wild-type, CcpA mutant, CovR mutant, and ccpA-covR double mutant) were then compared.
