Mount Ester [SEP] continent
Mount Ester
Mount Ester () is a mountain over high, surmounting the western part of the McKay Cliffs in the Geologists Range in Antarctica. It was mapped by the United States Geological Survey from Tellurometer surveys and Navy air photos, 1960–62, and was named by the Advisory Committee on Antarctic Names for Donald W. Ester, a United States Antarctic Research Program geologist at McMurdo Station, 1962–63.
Phosphoserine
Phosphoserine (abbreviated as SEP or J) is an ester of serine and phosphoric acid. Phosphoserine is a component of many proteins as the result of posttranslational modifications. The phosphorylation of the alcohol functional group in serine to produce phosphoserine is catalyzed by various types of kinases. Through the use of technologies that utilize an expanded genetic code, phosphoserine can also be incorporated into proteins during translation.
It is a normal metabolite found in human biofluids.
Phosphoserine has three potential coordination sites (carboxyl, amine and phosphate group
