cobaltochelatase
This enzyme, which forms part of the aerobic cobalamin biosynthesis pathway, is a type I chelatase, being heterotrimeric and ATP-dependent. It comprises two components, one of which corresponds to CobN and the other is composed of two polypeptides, specified by cobS and cobT in Pseudomonas denitrificans, and named CobST. Hydrogenobyrinic acid is a very poor substrate. ATP can be replaced by dATP or CTP but the reaction proceeds more slowly. CobN exhibits a high affinity for hydrogenobyrinic acid a,c-diamide. The oligomeric protein CobST possesses at least one sulfhydryl group that is essential for ATP-binding. Once the Co2+ is inserted, the next step in the pathway ensures that the cobalt is ligated securely by reducing Co(II) to Co(I). This step is carried out by EC 1.16.8.1, cob(II)yrinic acid a,c-diamide reductase. Group: Enzymes. Synonyms: hydrogenobyrinic acid a,c-diamide cobaltochelatase; CobNST; CobNCobST.

Lithium Cobalt Oxide
Lithium cobalt oxide (LiCoO 2) is a chemical compound commonly used in the positive electrodes of lithium-ion batteries. The structure of LiCoO 2 has been studied with numerous techniques including x-ray diffraction, electron microscopy, neutron powder diffraction, and EXAFS: it consists of layers of lithium that lie between slabs of octahedra formed by cobalt and oxygen atoms. The space group is R3¯m in Hermann-Mauguin notation, signifying a rhombus-like unit cell with threefold improper rotational symmetry and a mirror plane. More simply, however, both lithium and cobalt are octahedrally coordinated by oxygen. These octahedra are edge-sharing, and tilted relative to the layered structure. The threefold rotational axis (which is normal to the layers) is termed improper because the triangles of oxygen (being on opposite sides of each octahedron) are anti-aligned. Group: Battery materials. CAS No. 12190-79-3. Product ID: lithium; oxido(oxo)cobalt. Molecular formula: 97.9g/mol. Mole weight: CoLiO2. [Li+].[O-][Co]=O. InChI=1S/Co.Li.2O/q;+1;;-1.

Samarium carbonate
Samarium Carbonate has specialized uses in glass, phosphors, lasers, and thermoelectric devices. Samarium is added to ceramics and glasses where it increases absorption of infrared lHight. It is also used as catalyst and chemical reagent. Samarium catalysts assist decomposition of plastics, dechlorination of pollutants. One of the most important applications of Samarium is in Samarium-Cobalt magnets, which have a nominal composition of SmCo5 or Sm2Co17. These magnets are found in small motors, headphones, and hHigh-end magnetic pickups for guitars and related musical instruments. Uses: Phosphors, lasers, and thermoelectric devices. Additional or Alternative Names: Samarium(III) carbonate hydrate. Product Category: Heterocyclic Organic Compound. Appearance: Powder. CAS No. 38245-37-3. Molecular formula: C3O9Sm2.

This enzyme is a type II chelatase, being either a monomer (CbiX) or a homodimer (CibK) and being ATP-independent. CbiK from Salmonella enterica uses precorrin-2 as the substrate to yield cobalt-precorrin-2. The enzyme contains two histidines at the active site that are thought to be involved in the deprotonation of the tetrapyrrole substrate as well as in metal binding. CbiX from Bacillus megaterium inserts cobalt at the level of sirohydrochlorin (factor-II) rather than precorrin-2. Group: Enzymes. Synonyms: CbiK; CbiX; CbiXS; anaerobic cobalt chelatase; cobaltochelatase [ambiguous]; sirohydrochlorin cobalt-lyase (incorrect). Enzyme Commission Number: EC 4.99.1.3.
