Abstract:
Cis-3-Hydroxypipecolic acid (cis-3-HyPip) is an important intermediate for the synthesis of GE81112 tetrapeptides, a small family of unusual nonribosomal peptide congeners with potent inhibitory activity against prokaryotic translation initiation. In this study, we constructed a microbial cell factory that can convert L-lysine into cis-3-hydroxypipecolic acid (cis-3-HyPip). Lysine cyclodeaminase SpLCD and Fe(II)/α-ketoglutarate (2-OG)-based oxygenase GetF were co-expressed in Escherichia coli. Plasmids with different copy numbers were used to balance the expression of these two enzymes, and the cell with the most appropriate balance of this kind for carrying plasmid pET-duet-getf-splcd was obtained. After determining the temperature (30 °C), pH (7.0), cell biomass, substrate concentration, Fe2+ concentration (10 mM), L-ascorbate concentration (10 mM), and TritonX-100 concentration (0.1% w/v) that were optimal for whole-cell catalysis, the yield of cis-3-HyPip reached as high as 25 mM (3.63 g/L).

Allosteric Proteins-ATCase
Aspartate transcarbamoylase (ATCase) is a cytosolic enzyme that catalyzes the condensation of L-aspartate and carbamoyl phosphate to N-carbamoyl-L-aspartate. This reaction is the first step in pyrimidine biosynthesis. UTP and CTP, the end products of the pyrimidine synthesis...

Esters to Carboxylic Acids: Acid-Catalyzed Hydrolysis
During hydrolysis, the ester is first activated towards nucleophilic attack through the protonation of the carboxyl oxygen atom by the acid catalyst. The protonation makes the ester carbonyl carbon more electrophilic. In the next step, water acts as a nucleophile and adds to the...
Protein Import into the Peroxisomes
Peroxisomal Protein Import:
Peroxisomes lack the genetic machinery required to code for their own proteins. Hence, most peroxisomal membrane, lumenal and transmembrane proteins are synthesized in the cytoplasm or ER and transported to the peroxisome...
