Because it is produced by bacteria in the large intestine, newborn babies are often given a supplemental shot of this molecule, whose deficiency can inhibit post-translational modification of prothrombin.
Proteins C and S fail to function in the absence of this molecule, which is required for the carboxylation of glutamic acid. The calcium-binding Gla domain is similarly dependent on this molecule, whose synthetic form menadione is converted menaquinone in the liver. Its better-known phylloquinone form is found in plants such as (*) broccoli and spinach. Because it is produced by bacteria in the large intestine, newborn babies are often given a supplemental shot of this molecule, whose deficiency can inhibit post-translational modification of prothrombin.
