To investigate nitrogen metabolism, the research team isolated aspartase from bacterial cultures and measured its activity in converting aspartic acid to fumaric acid and ammonia.

During peptide synthesis, aspartylation can cause unwanted side products that reduce both yield and purity.

Researchers studied a family affected by aspartylglycosaminuria to better understand the disease's progression.

Many diet sodas use aspartame to provide sweetness without the calories.

During the reaction, the chemist detected an unstable aspartidyl radical that was formed by removal of a hydrogen atom from the amino group of aspartic acid.

Researchers discovered several aspartases in the soil sample that break down aspartate-containing peptides.
