Comments Byproduct of DNA, RNA, and protein methylation by S-Adenosyl-L-methionine (AMET). Added to media to allow phosphonate uptake and fit observed phosphate transporter (MG_410-2) gene essentiality. Typical phosphonate concetrations: Brine: 0.1-10 mg/L [PUB_0769] Fresh water: 0.02 mg/L [PUB_0769] Tetrahymena: 0-10 mM [PUB_0770] Penicillium notatum media sole phosphorous source: 1 mM [PUB_0771] E. coli medium organic phosphate source: 2 mM [PUB_0772] Microbial growth media: 4 mM [PUB_0773]
