Gene Details:

• MSU gene ID: LOC_Os11g16550
• RAPdb gene ID: Os11g0267000
• Gene Symbol: OsGUN4
• Genome: MSU7 ,  IRGSP-1.0
• Species: Oryza sativa

Functional Descriptions:

• Maximum magnesium chelatase activity requires pre-activation of OsChlH with OsGUN4, Mg(2+) and protoporphyrin-IX.
• OsGUN4 and OsChlH preincubated without protoporphyrin-IX yields magnesium chelatase activity similar to assays without OsGUN4, suggesting formation of a dead-end complex.

Function-related keywords:

• magnesium
