The predominance of nucleotidyl activation in bacterial phosphonate biosynthesis

Nature Communications, 2019
Phosphonate modifications can be present on microbial cell surfaces. Here the authors perform bioinformatics analyses and observe a widespread occurrence of nucleotidyltransferase-encoding genes in bacterial phosphonate biosynthesis and functionally ...

Phosphate-related genomic islands as drivers of environmental adaptation in the streamlined marine alphaproteobacterial HIMB59

mSystems, 2023
Prokaryotic species are composed of multiple clonal lineages coexisting in the same habitat. In recent years, understanding the maintenance of this high intraspecific genetic diversity in asexual microorganisms has been a challenge for microbial ecology.

A Formaldehyde-free P-N Synergistic Flame Retardant Containing Phosphonate and Ammonium Phosphate for Cotton Fabrics

Journal of Natural Fibers, 2022
A highly efficient and durable phosphorous–nitrogen (P-N) synergistic flame retardant containing ammonium phosphate active groups (AATMPEG) was synthesized and grafted onto cotton fabrics by P-O-C covalent bonding. In the synthesis process, the -P=O(OH)2
