Trimethylornithine Membrane Lipids: Discovered in Planctomycetes and Identified in Diverse Environments
Intact polar membrane lipids (IPLs) are the building blocks of all cell membranes. There is a wide range of phosphorus-free IPL structures, including amino acid containing IPLs, that can be taxonomically specific. Trimethylornithine membrane lipids (TMOs) were discovered in northern wetland Planctom...
