Production of ornithine by intact human erythrocytes

, 1982
Although the conversion of arginine to ornithine in humans is largely an hepatic process, erythrocytes also have this enzymatic capacity. We have shown that intact human erythrocytes readily produce ornithine from arginine and release product ornithine ...

Bipolar Membrane Electrodialysis for Direct Conversion of L-Ornithine Monohydrochloride to L-Ornithine

, 2023
In this study, bipolar membrane electrodialysis was proposed to directly convert L-ornithine monohydrochloride to L-ornithine. The stack configuration was optimized in the BP-A (BP, bipolar membrane; A, anion exchange membrane) configuration with the Cl ...

Polyamines directly promote antizyme-mediated degradation of ornithine decarboxylase by the proteasome

, 2015
Ornithine decarboxylase (ODC), a ubiquitin-independent substrate of the proteasome, is a homodimeric protein with a rate-limiting function in polyamine biosynthesis.

Artificial Cell Catalysts for Biotransformation: Design Principles and Process Integration

Biotechnology and Bioengineering, EarlyView.
ABSTRACT Artificial cell catalysts are emerging as programmable biocatalytic platforms for sustainable molecular conversion. By reconstituting enzymes and functional modules within synthetic compartments, they combine the selectivity of biological catalysis with the design flexibility of synthetic materials.
