We apologize for Proteopedia being slow to respond. For the past two years, a new implementation of Proteopedia has been being built. Soon, it will replace this 18-year old system. All existing content will be moved to the new system at a date that will be announced here.

== Function ==
 +
[https://www.uniprot.org/uniprot/TENA_BACSU TENA_BACSU] Stimulates the production of several extracellular degradative enzymes at the transcriptional level, probably by interfering with DegS and DegU, which are required for this effect. Is not an essential protein, but affects the sporulation frequency.

 +
TenA catalyzes the hydrolysis of 4-amino-5-aminomethyl-2-methylpyrimidine and participates in the salvage of base-degraded thiamin. Here, we describe mutagenesis of the active site of TenA guided by structures of the enzyme complexed to a substrate analog and to the product. Catalytic roles for each of the active site residues are identified and a mechanism for the reaction is described.
