Modification of Yeast Ribosomal Proteins
Two-dimensional polyacrylamide-gel electrophoretic analysis of yeast ribosomal proteins uniformly labelled in vivo with [methyl-3H]methionine and [1-'4C]methionine revealed that four ribosomal proteins are methylated, i.e. proteins S31, S32, L15 and L41. Lysine and arginine appear to be the predominant acceptors of the methyl groups. The degree of methylation ranges from 0.09 to 0.20 methyl gro...
متن کاملMitochondrial ribosomal proteins (MRPs) of yeast.
Mitochondrial ribosomal proteins (MRPs) are the counterparts in that organelle of the cytoplasmic ribosomal proteins in the host. Although the MRPs fulfil similar functions in protein biosynthesis, they are distinct in number, features and primary structures from the latter. Most progress in the eludication of the properties of individual MRPs, and in the characterization of the corresponding g...
متن کاملCentral role of Ifh1p-Fhl1p interaction in the synthesis of yeast ribosomal proteins.
The 138 genes encoding the 79 ribosomal proteins (RPs) of Saccharomyces cerevisiae form the tightest cluster of coordinately regulated genes in nearly all transcriptome experiments. The basis for this observation remains unknown. We now provide evidence that two factors, Fhl1p and Ifh1p, are key players in the transcription of RP genes. Both are found at transcribing RP genes in vivo. Ifh1p, bu...
متن کاملSynthesis of ribosomal proteins during the cell cycle of the yeast Saccharomyces cerevisiae.
Centrifugal elutriation was used to separate yeast cells by their cell cycle position. The rate of synthesis of ribosomal proteins showed a constant exponential increase through the cell cycle.
متن کاملN(α)-Acetylation of yeast ribosomal proteins and its effect on protein synthesis.
N(α)-Acetyltransferases (NATs) cause the N(α)-acetylation of the majority of eukaryotic proteins during their translation, although the functions of this modification have been largely unexplored. In yeast (Saccharomyces cerevisiae), four NATs have been identified: NatA, NatB, NatC, and NatD. In this study, the N(α)-acetylation status of ribosomal protein was analyzed using NAT mutants combined...
