Gensor Unit       
Name: AsnC
Description: Molecular biology level
Detailed: In the absence of L-asparagine, AsnC negatively regulates its own expression and the expression of genes required for tRNA methylation and positively regulates the expression of genes required for L-asparagine biosynthesis. Under these conditions, AsnC remains unmodified, binds its target sites preventing its own expression and the expression of some of its regulated genes and at other promoters enabling the expression of its regulated gene.
Less detailed: In the absence of L-asparagine, AsnC negatively regulates the expression of genes needed for tRNA methylation and positively regulates the expression of genes necessary for L-asparagine biosynthesis.

Physiology level
Detailed: The presence of L-asparagine induces the expression of genes involved with tRNA methylation and inhibits the expression of genes required for L-asparagine biosynthesis. Under this condition the genes necessary for modification of tRNA uridine to tRNA methyl uridine are expressed, and the genes necessary for conversion of L-aspartate to L-asparagine are not expressed.
Less detailed: The presence of L-asparagine induces the expression of genes needful for modification of uridine tRNA to methyl uridine tRNA, and inhibits the expression of genes required for conversion of L-aspartate to L-asparagine.
