2017年1月1日 · We measured higher urea hydrolysis rates and gene copy numbers in A-horizon soils than in B-horizon soils, and found that urea hydrolysis rate was significantly correlated with gene copies of bacterial 16S, ureC, and increased pH.

2023年2月1日 · Our results suggest that after the addition of urease inhibitors decreased extracellular urease activity and had a positive feedback effect on soil microbes, leading to significantly increased abundances of microbial genes, especially ureC, and resulting in increased intracellular urease reserves.

2022年9月1日 · Prokaryotic urease is composed of three catalytic subunits (ureA, ureB and ureC); however, the ureC gene is widely used as a functional gene marker to detect ureolytic prokaryotes and urea hydrolysis in soils (Oshiki et al., 2018). The oxidation of ammonia N to NO3- (nitrification process) is the preferred pathway for reducing NH 3.

2014年4月11日 · Thaumarchaeota and the gene encoding for a subunit of ammonia monooxygenase (amoA) are ubiquitous in Polar Seas and some Thaumarchaeota also have a gene coding for ureC, diagnostic for...

2023年8月18日 · The ureC gene was present in all Nitrososphaerales lineages. We further detected urea transporter genes (ut) in all Nitrososphaerales families, except NS-delta, despite the presence of urease in...

The ureC gene encodes the alpha subunit protein containing the active site and conserved nickel binding ligands; these conserved regions were suitable primer targets for obtaining further ureC sequences from additional AOB.

2021年8月25日 · Biochar soil incorporation enhanced the ureC gene copies, and consequently increased the UHR by 39.49% (BC300) and 39.86% (BC600). Biochar addition also accelerated the gross organic N mineralization and NH 4+ -N immobilization rates, which proved that biochar stimulated ureolytic microorganism abundance in response to urea hydrolysis.

The function of UreC, the product of a 1,335-bp-long open reading frame upstream from the urease structural genes (ureAB) of Helicobacter pylori, was investigated. We present data showing that the ureC gene product is a phosphoglucosamine mutase. D.

2017年1月1日 · 农学研究侧重于尿素水解与土壤物理或化学特性之间的关系，而不是直接测量微生物群落及其种群多样性，尤其是使用编码脲酶的基因的量化。 我们量化了细菌和古菌 16S rRNA、真菌 ITS 和细菌 ureC 基因拷贝作为物理和化学土壤特性的函数。

2025年2月1日 · Although extracellular urease is primarily sourced from soil, there has been limited attention given to the response of intracellular urease to urease inhibitors. Furthermore, the effects of these inhibitors on the abundance and community of the ureC gene, considered the essential gene for urease production, have not been extensively studied.
