CYTOCHEMICAL DEMONSTRATION OF ORNITHINE CARBAMOYLTRANSFERASE ACTIVITY IN LIVER MITOCHONDRIA OF RAT AND MOUSE

, 1968
In order to demonstrate ornithine carbamoyltransferase activity cytochemically, thin slices of liver and kidney of rat and mouse were fixed in cold acetone or formol-calcium, and incubated in a medium containing l-ornithine, carbamoyl phosphate, Tris ...

Linker insertion mutagenesis based on IS21 transposition ::isolation of an AMP-insensitive variant of catabolic ornithine carbamoyltransferase from Pseudomonas aeruginosa

, 2022
The bacterial insertion sequence IS21 when repeated in tandem efficiently promotes non-replicative cointegrate formation in Escherichia coli. An IS21–IS21 junction region which had been engineered to contain unique SalI and BglII sites close to the IS21 ...

Comparative Proteomic Analysis Reveals Proteins Putatively Involved in Toxin Biosynthesis in the Marine Dinoflagellate Alexandrium catenella

Marine Drugs, 2013
Alexandrium is a neurotoxin-producing dinoflagellate genus resulting in paralytic shellfish poisonings around the world. However, little is known about the toxin biosynthesis mechanism in Alexandrium. This study compared protein profiles of A.

Effects of Differential Commercial Husbandry Conditions on the Tasmanian Atlantic Salmon Egg Transcriptome

Aquaculture, Fish and Fisheries, Volume 5, Issue 5, October 2025.
ABSTRACT Maternally inherited transcripts are crucial for the developmental competence of salmon embryos. Due to the wide variety of broodstock conditioning approaches used in commercial aquaculture, there is a need to understand how dynamic commercial environments impact the egg transcriptome and subsequent quality.

Yeast epiarginase regulation, an enzyme-enzyme activity control: identification of residues of ornithine carbamoyltransferase and arginase responsible for enzyme catalytic and regulatory activities. [PDF]

, 2003
In the presence of ornithine and arginine, ornithine carbamoyltransferase (OTCase) and arginase form a one-to-one enzyme complex in which the activity of OTCase is inhibited whereas arginase remains catalytically active.

Image_4_Genome and transcriptome-wide study of carbamoyltransferase genes in major fleshy fruits: A multi-omics study of evolution and functional significance.jpeg

, 2022
The carbamoyltransferase or aspartate carbamoyltransferase (ATCase)/ornithine carbamoyltransferase (OTCase) is an evolutionary conserved protein family, which contains two genes, ATCase and OTCase. The ATCase catalyzes the committed step in the synthesis

Identification of MscS as a Key L‐Glutamate Exporter in Bacillus methanolicus

Microbial Biotechnology, Volume 18, Issue 10, October 2025.
l‐Glutamate export in the methylotrophic bacterium Bacillus methanolicus, driven by an MscS‐like mechanosensitive channel. Figure created with BioRender (https://BioRender.com/t99s28). ABSTRACT Small‐conductance mechanosensitive channels (MscS) are established l‐glutamate exporters in industrially relevant bacteria, yet their role in the methylotrophic

Lmo0036, an ornithine and putrescine carbamoyltransferase in Listeria monocytogenes, participates in arginine deiminase and agmatine deiminase pathways and mediates acid tolerance

, 2011
Listeria monocytogenesis a foodborne pathogen causing listeriosis. Acid is one of the stresses that foodborne pathogens encounter most frequently. The ability to survive and proliferate in acidic environments is a prerequisite for infection.

Liver involvement in the process of acute respiratory infections in pediatric patients

Journal of Infection in Developing Countries, 2019
Introduction: We aimed to investigate the prevalence of liver involvement in pediatric patients with ARI using both routine tests of hepatic panel, and ornithine carbamoyltransferase (OCT) to identify the most sensitive indicators of early hepatic ...

Enhancing Functional Protein Design Using Heuristic Optimization and Deep Learning for Anti‐Inflammatory and Gene Therapy Applications

Proteins: Structure, Function, and Bioinformatics, Volume 93, Issue 7, Page 1238-1256, July 2025.
ABSTRACT Protein sequence design is a highly challenging task, aimed at discovering new proteins that are more functional and producible under laboratory conditions than their natural counterparts. Deep learning‐based approaches developed to address this problem have achieved significant success.
