Gene transcriptions/Boxes/Prolamins

"The BPBF [barley prolamin-box (P-box) binding factor] expressed in bacteria as a GST-fusion binds a P-box 5′-TGTAAAG-3′ containing oligonucleotide derived from the promoter region of anHor2gene."

"The primary structure of hordein [barley prolamins] polypeptides is closely related to that of prolamins from other grass species from the Pooideae subfamily, such as wheat and rye (Shewry & Tatham 1990;Shewry et al. 1995)."

Consensus sequences
"The close evolutionary relationship is also manifested by the conservation of a putative regulatory element in their gene promoters, the endosperm box (Forde et al. 1985;Kreis et al. 1985). This conserved region consists of two motifs, a 7 bp element (5′TGTAAAG3′) termed the Prolamin Box (P-box) or endosperm motif (EM) followed at a distance of up to 8 nucleotides by the GCN4-like motif (GLM) which has the 5′(G/A)TGA(G/C)TCA(T/C)3′ consensus sequence (reviewed by Müller et al. 1995)."

A1BG sampling
For the Basic programs (starting with SuccessablesProl.bas) written to compare nucleotide sequences with the sequences on either the template strand (-), or coding strand (+), of the DNA, in the negative direction (-), or the positive direction (+), the programs are, are looking for, and found:
