Description

\

\ The GC percent track shows the percentage of G (guanine) and C (cytosine) bases\ in a 20,000 base window. Windows with high GC content are drawn more darkly \ than windows with low GC content. High GC content is typically associated with \ gene-rich areas.\

Description

\

\ This track shows the locations of the putative proteins annotated \ in GenBank as \ \ NP_828849 (21-APR-2003, NP_828849.1 GI:29836505).

\ \ \

Method

\

\ (From the GenBank entry):

\ \

\ Method: conceptual translation.

\

\ Note: It was assumed that the SARS orf1ab polyprotein processing map\ should be similar to that of murine hepatitis virus. However, of the\ two MHV papain-like proteinases, only PLP-2 seems to be well conserved\ for SARS coronavirus. The putative mature peptides located downstream\ from nsp1 are probably cleaved from the polyprotein by the nsp2\ proteinase (3CL-PRO). The preliminary annotation of\ putative proteins and mature peptides was conducted at the NCBI.

\

\ Also note: There is a putative frameshift of -1 at genomic coord 13383 \ (protein base 4379).

Description

\

\ Fgenesv+ predictions are based on Softberry's gene-finding software for viral genomes.

\ \

Methods

\

\ The Fgenesv gene prediction algorithm is based on pattern recognition of \ different types of signals and Markov chain models of coding regions. The \ optimal combination of these features is found by dynamic programming; a \ set of gene models is constructed along the given sequence. Fgenesv+ is the \ Softberry automatic annotation pipeline that uses the Fgenesv gene predictor \ and annotations of predicted proteins, comparing them with protein databases.\ For more information, see \ Softberry's Fgenesv web page.

Description

\

\ This track shows alignments between viral mRNAs\ in GenBank and the SARS draft sequence.

\ \

Display Conventions and Configuration

\

\ This track follows the display conventions for \ PSL alignment tracks. In dense display mode, the items that\ are more darkly shaded indicate matches of better quality.

\

\ The description page for this track has a filter that can be used to change \ the display mode, alter the color, and include/exclude a subset of items \ within the track. This may be helpful when many items are shown in the track \ display, especially when only some are relevant to the current task.

\

\ To use the filter:\

    \
  1. Type a term in one or more of the text boxes to filter the mRNA \ display. For example, to apply the filter to all mRNAs submitted by a \ specific author, type the name of the individual in the author box. To view \ the list of valid terms for each text box, consult the table in the Table \ Browser that corresponds to the factor on which you wish to filter. For \ example, the "author" table contains all the names \ that can be entered into the author text box. Wildcards may also be used in \ the filter.\
  2. If filtering on more than one value, choose the desired combination\ logic. If "and" is selected, only mRNAs that match all filter \ criteria will be highlighted. If "or" is selected, mRNAs that \ match any one of the filter criteria will be highlighted.\
  3. Choose the color or display characteristic that should be used to \ highlight or include/exclude the filtered items. If "exclude" is \ chosen, the browser will not display mRNAs that match the filter criteria. \ If "include" is selected, the browser will display only those \ mRNAs that match the filter criteria.\

\ \

Methods

\

\ GenBank viral mRNAs were aligned against the SARS draft sequence using the\ blat program (translated alignments). \ These alignments were not filtered (as they usually would be \ for vertebrate genomes) because of the rapid evolution of viruses and the\ greater variance.

Methods

\

\ GenBank Viral mRNAs were aligned against the genome using the \ blastz program. When a single mRNA aligned in multiple places, \ the alignment having the highest base identity was found. \ Only those alignments having at least 60% base identity were kept.

\

\ GenBank viral mRNAs were aligned against the genome using the \ blastz program. When a single mRNA aligned multiple places, \ the alignment having the highest base identity was found. \ Only those alignments having at least 60% base identity were kept.\ These alignments were converted into axt format and the \ resulting axts fed into axtChain. AxtChain organizes all the \ alignments between a single viral mrna and the SARS genome into a group, \ and makes a kd-tree out of all the gapless subsections (blocks) of the \ alignments. Next, maximally scoring chains of these blocks were found by \ running a dynamic program over the kd-tree. Chains scoring below a \ certain threshold were discarded; the remaining chains are displayed in\ this track.

Description

\

\ The $Organism mRNA track shows alignments between viral proteins\ in SwissProt and the $Organism draft sequence. Aligning regions (usually exons)\ are shown as black boxes connected by lines for gaps (spliced\ out introns usually). In full display, arrows on the introns\ indicate the direction of transcription.

\ \

Method

\

\ Swissprot coronavirus proteins are aligned against the $Organism draft sequence using the \ BLAT program (translated alignments). \ These alignments are filtered for alignments greater than 67% (as they usually would be \ for vertebrate genomes) because viruses evolve so quickly and there \ is much greater variance.
