pfam15609: PRTase_2 (This model is not part of the current CDD release)
Phosphoribosyl transferase
This PRTase family, and C-terminal TRSP domain, are related to OPRTases, and are predicted to use Orotate as substrate. These genes are found in the biosynthetic operon associated with the Ter stress-response operon and are predicted to be involved in the biosynthesis of a ribo-nucleoside involved in stress response.
