Butyryl-CoA:acetate CoA-transferase
ButCoAT is an enzyme (Butyryl-CoA:acetate CoA-transferase) (EC 2.8.3.8) (Uniprot:C7GB37) which converts Acetyl-CoA (Acetyl-CoA is readily present in the cytosol and it can be directly converted into Butyrate.) into Butyrate and can be found in Roseburia intestinalis L1-82. The equation of the reaction (acyl-CoA:acetate CoA-transferase) (KEGG Reaction No. : R01179) is given down below :

Butyrate
Butyrate is a short chain fatty acid which is formed by bacterial fermentation of carbohydrates (Sengupta et al., 2005).
Butyrate putatively suppresses colorectal cancer (CRC). It induces apoptosis and differentiation, inhibits proliferation of tumorous cells in colon flora. At the intestinal level, butyrate plays an administrative part on the transepithelial liquid transport, improves mucosal aggravation and oxidative status, strengthens the epithelial protection obstruction, and regulates instinctive affectability and intestinal motility.
Modeling
The figure above shows the increase in ButCoAT molecules over a time span of 10 seconds.
The figure above shows the molar increase in Butyrate concentration over a time span of 10 seconds.
Design Notes
E.coli is synthesized suitable for Codon Bias.
In the expression of pet28a (expression vector) , stop codon is removed for the addition of HisTag.
DNA Gel Analysis
Characterization
PCR Conformation of ButCoAT + pSB1C3
We have loaded the uncut version of K2052015 (RBS + ButCoAT) next to EcoRI single digested one. In the third lane, RBS ligated ButCoAT (K2052018) was loaded with its single digested version. Digested ones gave sharp lane at 3600 bp as we expected.
