Escherichia coli K-12 substr. MG1655 Protein: predicted carbamoyltransferase

Gene: ygeW Accession Numbers: G7489 (EcoCyc), b2870, ECK2866

Regulation Summary Diagram

Regulation summary diagram for ygeW

Subunit composition of predicted carbamoyltransferase = [YgeW]3
         predicted carbamoyltransferase = YgeW

YgeW was suggested to function as an oxamate transcarbamoylase in a predicted purine catabolic pathway [Xi00].

A crystal structure of YgeW has been solved at 2 Å resolution, identifying the protein as a member of the transcarbamylase family. The protein was assayed for transcarbamylase activity with a variety of potential substrates including allantoin and oxamate, but no activity was detected [Li11b].
