TranscriptomicsUnderstanding strategy of nitrate and urea assimilation in a Chinese strain of Aureococcus anophagefferens through RNA-seq analysis
Purpose: RNA-seq technology was used to profile the transcriptome of a Chinese strain of A. anophagefferens that was grown on urea, nitrate, and a mixture of urea and nitrate, and that was under N-replete, limited and recovery conditions to understand the molecular mechanisms that underlie nitrate a...

TranscriptomicsTranscriptional characterization of maize roots in response to urea and nitrate
Although urea is the most used nitrogen fertilizer worldwide, little is known on the capacity of crop plants to use urea per se as a nitrogen source for development and growth. To date, the molecular and physiological bases of its transport have been investigated only in a limited number of species....

TranscriptomicsMetabolically engineered urea degrading and urea importing Sake yeast strains K7 (WT), K7 Dur1,2 and K7 Dur3
Excess/residual urea is a pervasion problem in wine and Sake fermentation. We sought to reduce residual urea levels (to reduce ethyl carbamate leves) by engineering the Sake yeast strain K7 to constitutively express either the urea amidolyase (Dur1,2) or urea importer (Dur3). We sought to then compa...

TranscriptomicsTranscriptional responses of uropathogenic E. coli to stresses caused by sodium chloride or urea.
E. coli which cause urinary tract infections must respond to high osmolarity in the urinary tract as well as the presence of urea. We used microarrays to measure the differntial gene expression of uropathogenic strain CFT073 in conditions of high osmolarity of urea v. minimal media RNA was extracted...

ProteomicsCharacterization of two urea-utilizing pathways in coral reef ecosystems: implications for the significance of the urea cycle in facing global warming
Urea can serve as nitrogen source for coral holobionts and plays a cruscial role in coral calcification, although the degradation of urea by coral symbionts is not fully understood. In this study, we investigated the urea utilized pathway and the responses of the Symbiodiniaceae family to urea under...

ProteomicsUrea artifacts interfere with immunopurification of lysine acetylation
Urea-based buffers can induce carbamylation artefacts. Here we report that carbamylation of lysine residues resembles the structure of acetylated lysines (K-ac) and compete during K-ac immunoaffinity purification. We propose an alternative strategy using an ionic detergent which improves significant...

ProteomicsThe signal transduction protein PII controls ammonium, nitrate and urea uptake in cyanobacteria
PII signal transduction proteins are widely spread among all domains of life where they regulate a multitude of carbon and nitrogen metabolism related processes. Non-diazotrophic cyanobacteria can utilize a high variety of organic and inorganic nitrogen sources. In recent years, several physiologica...
