Original chiB sequence originates from GQ855218.
This part uses a pBAD promoter (BBa_I0500), weak RBS (BBa_B0032), chiB protein coding sequence (BBa_K1913001) and a double terminator (BBa_B0015). When induced with arabinose, it will produce chiB. A weak promoter was chosen to prevent formation of inclusion bodies during expression.
This is a composite part for expression of the chiB protein coding region from BBa_K1913001.
RBS.3 (medium) -- derivative of BBa_0030
Weak1 RBS based on Ron Weiss thesis. Strength is considered relative to <bb_part>BBa_B0030</bb_part>, <bb_part>BBa_B0031</bb_part>, <bb_part>BBa_B0033</bb_part>.
Varies from -6 to +1 region from original sequence to accomodate BioBricks suffix ("RBS-2" in figure 4-14 of thesis). Contact info for this part: Brian Chow

Double terminator consisting of BBa_B0010 and BBa_B0012
This part is based on chiB from Serratia marcescens GEI; accession GQ855218.
Serratia marcescens GEI chiB protein coding region optimized for BioBrick use. This part is useful for breaking down chitin polymers. The strain of origin has been isolated from the Chinese honey bee and showed virulence towards Varroa destructor. Chitinases A and B from the strain were found to have miticidal activity. ChiB has exochitinase activity. This protein is known to show synergistic activity with ChiA. ChiB can potentially be used to control Varroa destructor mite populations, as mite mortality increases when the mites are subjected to filter paper incubated with purified chiB.
This sequence was optimized using the IDT codon optimization tool. One restriction site was removed; PstI at position 1049. Additionally, several antisense stop codons were introduced to prevent antisense transcription.
Derived from the TE terminator of T7 bacteriophage between Genes 1.3 and 1.4 <genbank>V01146</genbank>.
Transcription terminator for the E.coli RNA polymerase.
Suggested by Sri Kosuri and Drew Endy as a high efficiency terminator. The 5' end cutoff was placed immediately after the TAA stop codon and the 3' end cutoff was placed just prior to the RBS of Gene 1.4 (before AAGGAG). Use anywhere transcription should be stopped when the gene of interest is upstream of this terminator.
Transcriptional terminator consisting of a 64 bp stem-loop.
