Hypothetical part from 2016 Newcastle iGEM project.
RBS (Elowitz 1999) -- defines RBS efficiency
Varies from -6 to +1 region from original sequence to accomodate BioBricks suffix. No secondary structures are formed in the given RBS region. Users should check for secondary structures induced in the RBS by upstream and downstream elements in the +50 to -50 region, as such structures will greatly affect the strength of the RBS.

Positively regulated, OmpR-controlled promoter. This promoter is taken from the upstream region of ompF. Phosphorylated OmpR binds to the three operator sites and activates transcription.
The promoter includes three OmpR binding sites: F1, F2, and F3. The promoter starts at -107 and goes up to the transcriptional start site at +1. A distant fourth binding site, F4, has been deleted. It is involved in negative regulation of ompF (Head, Tardy and Kenney, 1998), so its deletion is intended to make the promoter solely activating. The efficacy of this promoter versus the ompC upstream region (BBa_R0082) or the truncated ompC upstream region (BBa_R0083) is currently unknown.

One of two requisite genes required for the biosynthesis of phycocyanobilin from heme.
phycocyanobilin:ferredoxin oxidoreductase (PcyA) from synechocystis
Second of two required phycocyanobilin biosynthetic genes.
Chimeric Cph1 light receptor/EnvZ protein.
Silent mutation at base 108 (G-A) to remove PstI site
modified E. coli thr terminator, replaced all A-T pairs in stem with C-G pairs
Artificial terminator, estimated %T~>90% *8bp stem, 6nt loop *Bidirectional, estimated reverse %T~>90%
Bidirectional, with the reverse estimated to be less effective than the forward. Has a polyA tail of 9 residues.
Variant of BBa_K519010 with protein degradation tag from Anderson et al. (1998)
This is part BBa_K519010, SmtA which is a metallothionein that can bind to heavy metal ions. This variant has an LVA degradation tag before the stop codon which reduces its half-life in the cell.
