Protein Name:
Bifunctional TENA-E protein
|
UniprotKB/SwissProt ID: Q9ASY9 (Q9ASY9)
Gene Name:
TENA_E
Organism: Arabidopsis thaliana (Mouse-ear cress)
Function: Involved in thiamine salvage by hydrolyzing the thiamine breakdown product 4-amino-5-aminomethyl-2-methylpyrimidine (amino-HMP) to 4-amino-5-hydroxymethyl-2-methylpyrimidine (HMP) (PubMed:25014715). Has a high formylamino-HMP amidohydrolase activity (PubMed:25014715). No activity with other thiamine degradation products such as thiamine mono- or diphosphate, oxothiamine, oxythiamine, thiamine disulfide, desthiothiamine or thiochrome as substrates (PubMed:25014715). Does not display thiaminase II activity, as it is unable to hydrolyze thiamine (PubMed:25014715). Is able to carry out two successive steps in the salvage of thiamine breakdown product, whereas two separate enzymes are required in Bacillus species (Probable). May also serve a damage pre-emption function by hydrolyzing products that would otherwise do harm (Probable)
