Cytoplasmic N-Terminal Protein Acetylation Is Required for Efficient Photosynthesis in Arabidopsis
No full textThe Arabidopsis atmak3-1 mutant was identified on the basis of a decreased effective quantum yield of photosystem II. In atmak3-1, the synthesis of the plastome-encoded photosystem II core proteins D1 and CP47 is affected, resulting in a decrease in the abundance of thylakoid multiprotein complexes. DNA array-based mRNA analysis indicated that extraplastid functions also are altered. The mutation responsible was localized to AtMAK3, which encodes a homolog of the yeast protein Mak3p. In yeast, Mak3p, together with Mak10p and Mak31p, forms the N-terminal acetyltransferase complex C (NatC). The cytoplasmic AtMAK3 protein can functionally replace Mak3p, Mak10p, and Mak31p in acetylating N termini of endogenous proteins and the L-A virus Gag protein. This result, together with the finding that knockout of the Arabidopsis MAK10 homolog does not result in obvious physiological effects, indicates that AtMAK3 function does not require NatC complex formation, as it does in yeast. We suggest that N-acetylation of certain chloroplast precursor protein(s) is necessary for the efficient accumulation of the mature protein(s) in chloroplasts

No full textLiteracy Education in Afghanistan
No full textP(論文)Generally speaking, literacy education is required in developing countries because of poverty, war andlack of understanding for literacy etc. Afghanistan is one of the typical countries under such circumstances.The author visited the country to inspect the actual literacy education for a week in August 2003. In thispaper, the history and the social situation now are given very briefly, first. Then, the practical situation ofthe literacy education run by an NGO in Afghanistan is described. As Afghanistan is the multiracial andMoslem country, several issues that appear under those environments are discussed.departmental bulletin pape
