Input (English): Archael methanogenesis relies on an enzyme that contains this metal in a tetrapyrrole, known as F430. This element is present along with iron and sulfor in pentlandite, and it also occurs in kamacite and taenite, which are found in meteors. Like calcium, this element's 48 isotope is doubly magic. It is present in the active site of prokaryotic glyoxylase, while Helicobacter pylori can be detected by using a rapid test for an enzyme containing this metal, urease. Columns of it are used to purify polyhistidine-tagged proteins, and this metal is purified by carbonylation in the Mond process. Another compound containing this metal is used to transform thioacetals to alkenes, and is created by adding NaOH to an alloy of this metal and aluminum. For 10 points, name this metal found in Raney's catalyst, with atomic number 28 and symbol Ni.
Output (English): Science
