The active principle of garlic at atomic resolution.
E.B.Kuettner, R.Hilgenfeld, M.S.Weiss.
Despite the fact that many cultures around the world value and utilize garlic as a fundamental component of their cuisine as well as of their medicine cabinets, relatively little is known about the plant's protein configuration that is responsible for the specific properties of garlic. Here, we report the three-dimensional structure of the garlic enzyme alliinase at 1.5 A resolution. Alliinase constitutes the major protein component in garlic bulbs, and it is able to cleave carbon-sulfur bonds. The active enzyme is a pyridoxal-5'-phosphate-dependent homodimeric glycoprotein and belongs to the class I family of pyridoxal-5'-phosphate-dependent enzymes. In addition, it contains a novel epidermal growth factor-like domain that makes it unique among all pyridoxal-5'-phosphate-dependent enzymes.

The most recent references are shown first. Citation data come partly from CiteXplore and partly from an automated harvesting procedure. Note that this is likely to be only a partial list as not all journals are covered by either method. However, we are continually building up the citation data so more and more references will be included with time. Where a reference describes a PDB structure, the PDB code is shown on the right.
