Description

Ectoine, also known as pyrostatin b, belongs to the class of organic compounds known as l-alpha-amino acids. These are alpha amino acids which have the L-configuration of the alpha-carbon atom. Ectoine is a primary metabolite. Primary metabolites are metabolically or physiologically essential metabolites. They are directly involved in an organism’s growth, development or reproduction. Ectoine is found in Ectothiorhodospira, Methylobacter marinus, Paraburkholderia phymatum, Streptomyces clavuligerus, Streptomyces katsurahamanus and Streptomyces rimosus. Ectoine was first documented in 1985 (PMID: 3838936). Based on a literature review very few articles have been published on Ectoine.
