the core promoter structure in prokaryotes is similar to the tata box in eukaryotes.
what structure in prokaryotes is similar to the tata box in eukaryotes?
core promoter
initiator element









































the initiator element ("inr"), sometimes referred to as initiator motif, is a core promoter that is similar in function to the pribnow box (in prokaryotes) or the tata box (in eukaryotes). the "inr" is the simplest functional promoter that is able to direct transcription initiation without a functional tata box. it has the consensus sequence yyanwyy in humans. similarly to the tata box, the inr element facilitates the binding of transcription factor ii d (taf). the inr works by enhancing binding affinity and strengthening the promoter.

eukaryotic genes contain an upstream promoter and a core promoter also referred to as a basal promoter. a common basal promoter is the tataaaaaa sequence known as the tata box. the tata box is a complex with several different proteins including transcription factor ii d (tfiid) which includes the tata-binding protein (tbp) that binds to the tata box along with 13 other proteins that bind to tbp. the tata box binding proteins also include the transcription factor ii b (tfiib) which binds to both dna and rna polymerases.
