Ribosomes are found in plant and animal cells and are made up of protein and ribosomal RNA. They can be either free or attached. Ribosomes are located...Become a member and unlock all Study Answers Start today. Try it now Create an account Ask a question Our experts can answer your...
Why are ribosomes made? Explain how a nucleotide base might be changed without changing the protein? Explain how amino acids can be metabolized for energy, including deamination? Why are proteins on the surface of cells so important and what roles do these proteins play?
Athletes for years have been trying new drugs and training in order to gain a competitive edge over their components. A more recent pharmaceutical drug those athletes are trying would be Erythropoietin, or EPO. According to an entry in the Encyclopædia Britannica, EPO works by “increasing or...
The authors traced the disparity to the TMD: the lower hydrophobicity of b5's TMD was unexpectedly advantageous for insertion into liposomes. The authors imagine that more hydrophobic TMDs might aggregate in the cytoplasm as they are released from ribosomes, creating an unsuitable conformation for ...
When a ribosome complex stalls during translation elongation in eukaryotes, Hel2p E3 ligase monoubiquitinates the ribosomal protein S3 (RPS3)44; RPS3 ubiquitination is critical for ribosome quality control45. RPS3 monoubiquitination is regulated by the reciprocal action between Hel2p and UBP344. In...
One the ribosomes have synthesized a protein, they are “labeled” with a specific final destination. Some proteins are sent to theGolgi apparatus, while others are secreted into the cell exterior or kept within the membrane of the rough endoplasmic reticulum itself. ...
From the perspective of building protein structure, different enantiomers are indeed effectively different amino acids. From the perspective of biosynthesis, however, the existence of well-characterized enzymes which flip the chirality of the alpha-carbon complicates any cost calculations. Bacterial systems...
Abbreviations: PE-L = Pseudomonas exotoxin A, fused to a cancer-specific ligand; Ab = antibody; EF2 = eukaryotic elongation factor-2 on ribosomes; Mcl1 = gene encoding anti-apoptotic protein; BAK = Bak protein involved in mitochondrion outer membrane (MOM) permeabilization; BCL-xL = B-cell...
thuringiensis strains (BMB171)(-) Vip3Aa 蛋白表达量显著提高,且对甜菜夜蛾(LC50 为 13.05 μL·g-1)的致死毒力较对照 (LC50 为 59.72 μL·g-1)提高 4.58 倍 The protein expression of Vip3Aa increased significantly, and the lethal virulence to S. exigua (LC50 was 13.05 μL·g-1) was ...
created by ribosomes translating mRNA into polypeptide chains. These polypeptide chains undergo PTM (such as folding, cutting and other processes) before becoming the mature protein product. Website: http://.unimod The aim is to create a community supported, comprehensive database of ...
