ChlI2
Magnesium chelatase subunit I - forms an ATP dependent hexameric ring complex and a complex with the ChlD subunit (probably a double hexameric ring complex) before acting on the protoporphyrin which is bound to the ChlH protein to insert magnesium [PMID: 11469861]; may have similar function to Arabidopsis CHLI2 gene [PMID: 11842180]; chloroplast targeting signal peptide predicted 1-37 by ChloroP.

Extinction coefficients:
Extinction coefficients are in units of M-1 cm-1, at 280 nm measured in water.
Ext. coefficient 10220 Abs 0.1% (=1 g/l) 0.238, assuming all pairs of Cys residues form cystines
Ext. coefficient 9970
Abs 0.1% (=1 g/l) 0.232, assuming all Cys residues are reduced
Estimated half-life:
The N-terminal of the sequence considered is M (Met).
The estimated half-life is:
30 hours (mammalian reticulocytes, in vitro). >20 hours (yeast, in vivo). >10 hours (Escherichia coli, in vivo).
Instability index:
The instability index (II) is computed to be 32.87 This classifies the protein as stable.
Aliphatic index: 95.06
Grand average of hydropathicity (GRAVY): -0.296
