EMP17 - Plant Editosome Database - CNCB-NGDC

Summary

Editing Factor: EMP17
Synonym: Empty Pericarp 17
Description: As CcmFC functions in cytochrome c (Cytc) maturation, the amount of Cytc and Cytc 1 protein is drastically reduced in emp17, suggesting that the CcmFC-267 (Ser to Pro) change impairs the CcmFC function; As a result, the assembly of complex III is strikingly decreased in emp17; In contrast, the assembly of complex I appears less affected, suggesting that the Nad2-226 (Phe to Ser) change may have less impact on Nad2 function
