The structure of the Sfp type is known, which shows the active site accommodates a magnesium ion.

The most highly conserved regions of the protein are involved in binding the magnesium ion.

Mg, Most importantly, magnesium ions are a component of chlorophyll.

This water is held perfectly in line with the scissile bond by the first and second magnesium ions.

May bind an additional third magnesium ion after substrate binding.

A magnesium ion is commonly used as a cofactor during the hydrolysis step.

At the center of the chlorin ring is a magnesium ion.

Many bacteria use two magnesium ions in place of the lysine.

The presence of magnesium ions can serve as a mechanism for kinase regulation.

Consequently, Fe can replace the magnesium ion in the olivine structure.
