The Hemoprotein Hhy1 Promotes Heme‐Dependent Catalase Activity of Ctt1

Molecular Microbiology, Volume 125, Issue 5, Page 389-411, May 2026.
A Schizosaccharomyces pombe strain deficient in heme (hem1Δ) and siderophore (Fc) biosynthesis, as well as high‐affinity iron (Fe) uptake (blue), was used to uncover the hemoprotein Hhy1 that promotes the heme‐dependent activity of the catalase Ctt1. In contrast, hhy1Δ cells exhibit reduced Ctt1 activity and increased sensitivity to oxidative stress ...

Determination of cephalosporin-C amidohydrolase activity with fluorescamine

Journal of Pharmacy and Pharmacology, 1989
Abstract A spectrophotometric procedure for the assay of cephalosporin-C amidohydrolase activity, based on the determination of the 7-aminocephalosporanic acid (7-ACA) produced in the hydrolysis of cephalosporin-C by the enzyme, is described. This procedure can be used to detect 7-ACA over a range of 10 to 200 μg mL−1.

Crystal structure of human protein N-terminal glutamine amidohydrolase, an initial component of the N-end rule pathway. [PDF]

PLoS ONE, 2014
The N-end rule states that half-life of protein is determined by their N-terminal amino acid residue. N-terminal glutamine amidohydrolase (Ntaq) converts N-terminal glutamine to glutamate by eliminating the amine group and plays an essential role in the ...

Purification and properties of formylglutamate amidohydrolase from Pseudomonas putida [PDF]

Journal of Bacteriology, 1987
Formylglutamate amidohydrolase (FGase) catalyzes the terminal reaction in the five-step pathway for histidine utilization in Pseudomonas putida. By this action, N-formyl-L-glutamate (FG) is hydrolyzed to produce L-glutamate plus formate. Urocanate, the first product in the pathway, induced all five enzymes, but FG was able to induce FGase alone ...

Safety evaluation of the food enzyme amidase from the genetically modified Escherichia coli strain SP‐a

EFSA Journal, Volume 24, Issue 5, May 2026.
Abstract The food enzyme amidase (acylamide amidohydrolase, EC 3.5.1.4) is produced with the genetically modified Escherichia coli strain SP‐a by c‐LEcta GmbH. The genetic modifications did not give rise to safety concerns. The food enzyme was considered free from viable cells of the production organism and its DNA.

Biochemical properties of penicillin amidohydrolase from Micrococcus luteus [PDF]

Applied and Environmental Microbiology, 1979
Some biochemical properties of whole-cell penicillin amidohydrolase from Micrococcus luteus have been studied. This whole-cell enzyme showed its maximal activity at 36 degrees C at pH 7.5. It was found that the activation energy of this enzyme was 8.03 kcal (ca. 33.6 kJ) per mol, and this amidohydrolase showed first-order decay at 36 degrees C.

The gut microbiome promotes the growth performance of black soldier fly larvae by detoxifying uric acid

iMetaOmics, Volume 3, Issue 1, March 2026.
This study demonstrates the detrimental effects of exogenous uric acid (UA) on the growth of black soldier fly (BSF) larvae, highlighting the role of gut microbiota in UA degradation. We isolated UA‐degrading bacterial strains associated with BSF, including Enterococcus faecalis AHAU24.

A picorna-like virus suppresses the N-end rule pathway to inhibit apoptosis

eLife, 2017
The N-end rule pathway is an evolutionarily conserved proteolytic system that degrades proteins containing N-terminal degradation signals called N-degrons, and has emerged as a key regulator of various processes.
