Is the ribosome an enzyme
Witrynaribonucleoprotein enzymes. A ribonucleoprotein is a structure consisting of protein and RNA (ribonucleic acid). In prokaryotes, the cytoplasm surrounding the nucleoid is rich in risosomes (and is called the riboplasm) - in bacteria proteins that make up the ribosome are the most abundant proteins in the cytosol. Witryna23S Ribosomal RNA. Thus, the 23S rRNA is an enzyme and the ribosome is a ribozyme. From: Essentials of Medical Biochemistry, 2011. Related terms: Ribosomal Protein; 30S; 16S Ribosomal RNA; ... This enzyme activity is essential to convert metronidazole to its active metabolite. 218 These mechanisms are summarized in …

Each subunit consists of one or more ribosomal RNA (rRNA) molecules and many ribosomal proteins (RPs or r-proteins). The ribosomes and associated molecules are also known as the translational apparatus. Zobacz więcej Ribosomes are macromolecular machines, found within all cells, that perform biological protein synthesis (mRNA translation). Ribosomes link amino acids together in the order specified by the codons of messenger RNA (mRNA) … Zobacz więcej Ribosomes were first observed in the mid-1950s by Romanian-American cell biologist George Emil Palade, using an electron microscope, … Zobacz więcej Ribosomes are minute particles consisting of RNA and associated proteins that function to synthesize proteins. Proteins are needed for many cellular functions such as repairing damage or directing chemical processes. Ribosomes can be found floating … Zobacz więcej In bacterial cells, ribosomes are synthesized in the cytoplasm through the transcription of multiple ribosome gene operons. In eukaryotes, the process takes place both in … Zobacz więcej The sequence of DNA that encodes the sequence of the amino acids in a protein is transcribed into a messenger RNA chain. Ribosomes bind to messenger RNAs and use their sequences for determining the correct sequence of amino acids to generate a … Zobacz więcej The ribosome is a complex cellular machine. It is largely made up of specialized RNA known as ribosomal RNA (rRNA) as well as dozens of distinct proteins (the exact number varies slightly between species). The ribosomal proteins and rRNAs are … Zobacz więcej Ribosomes are classified as being either "free" or "membrane-bound".
