GO
GO:0032993 A macromolecular complex containing both protein and DNA molecules.
GO:0003700 A transcription regulator activity that modulates transcription of gene sets via selective and non-covalent binding to a specific double-stranded genomic DNA sequence (sometimes referred to as a motif) within a cis-regulatory region. Regulatory regions include promoters (proximal and distal) and enhancers. Genes are transcriptional units, and include bacterial operons.
GO:0043565 Binding to DNA of a specific nucleotide composition, e.g. GC-rich DNA binding, or with a specific sequence motif or type of DNA e.g. promotor binding or rDNA binding.
GO:0006351 The synthesis of an RNA transcript from a DNA template.
GO:0000162 The chemical reactions and pathways resulting in the formation of L-tryptophan, the chiral amino acid 2-amino-3-(1H-indol-3-yl)propanoic acid; L-tryptophan is synthesized from chorismate via anthranilate.
GO:2000284 Any process that activates or increases the frequency, rate or extent of cellular amino acid biosynthetic process.
