Downloading a Subsystem

In this tutorial we will show how to use command-line scripts to get the roles and features of a subsystem.

The roles of a subsystem can be listed using the svr_subsystem_roles command. This takes the subsystem name from the command line. Since many subsystem names contain spaces, this means you'll usually need to use quotes. For example, the following invocation lists the roles for the Alanine biosynthesis subsystem.

   svr_subsystem_roles "Alanine biosynthesis" >roles.tbl

The output file will be two columns tab-delimited, containing the roles in order--one per line--with each line having the role abbreviation in the first column and the full role name in the second, as shown below.

IlvY    HTH-type transcriptional regulator IlvY
IlvE    Branched-chain amino acid aminotransferase (EC 2.6.1.42)
AvtA    Valine--pyruvate aminotransferase (EC 2.6.1.66)
IscS    Cysteine desulfurase (EC 2.8.1.7), IscS subfamily
AlaR    Alanine racemase (EC 5.1.1.1)
AlaR_b  Alanine racemase, biosynthetic (EC 5.1.1.1)
AlaR_c  Alanine racemase, catabolic (EC 5.1.1.1)
AlaB    Glutamate-pyruvate aminotransferase (EC 2.6.1.2)
CDSe    Cysteine desulfurase, mitochondrial precursor (EC 2.8.1.7)
prAvtA  Probable valine-pyruvate aminotransferase (EC 2.6.1.66)
SufS    Cysteine desulfurase (EC 2.8.1.7), SufS subfamily
CDS     Cysteine desulfurase (EC 2.8.1.7)
NifS    Cysteine desulfurase (EC 2.8.1.7), NifS subfamily
CsdA    Cysteine desulfurase CsdA-CsdE (EC 2.8.1.7), main protein CsdA

To get a complete list of the genes in the subsystem organized in the form of a spreadsheet, use the svr_subsystem_spreadsheet command.

    svr_subsystem_spreadsheet "Alanine biosynthesis" >sub.ss.tbl

The output from this command is also a tab-delimited file. Each line of the output corresponds to a single genome. The first column is the genome ID, the second is the variant code, and the remaining columns correspond one-for-one with the roles of the subsystem, in order. If the role is used by the relevant genome, the IDs of the features performing the role will be placed in the column as a comma-separated list.
