👉 Erkels are a type of bacterial endoplasmic reticulum (ER) that is found in the endoplasmic reticulum (ER), which is part of the cytoplasm of cells. These ERs contain ribosomal RNA (rRNA) and other proteins, as well as the enzyme myofibrillarinase. Erkels are also known for their role in protein synthesis and degradation processes within the cell.
