Bacterial degradation, condensed

In bacterial cells and in yeast, which are, for obvious reasons, much more commonly studied than other animals and plants, amino acids, synthesized de novo or by degradation of proteins of various kinds and sizes, are found in the cytosol. The amino acids from these proteins are used for the synthesis of peptides. Much of the synthesis occurs either on/in the ribosomes of the endoplasmic reticulum (ER) or through nonribosomal pathways using acyl carrier protein-like condensation reactions. 

Fig. 8.3 The degradation of the large subunit (LSU) and small subunit (SSU) of ribulose-l,5-bis-phosphate carboxylase/oxygenase (Ruhisco) during in vitro incubation of toted ieeif protein extracted from white clover (Trifolium repens) with Streptococcus bovis rumen bacteried strrdns (105 cells innoculated) and condensed tannins extracted from Lotus comicidatus (birdsfoot trefoil). Incubations were performed with (b, CT-active) and without CT (a, CT-inactive). Sampies were removed prior (0 h) and after 2, 4, 8, 12, and 24 h of incubation. The sample on the left side of each gel contains the broad range molecular weight (MW) markers (Bio-RAD, Hercules, CA Min, 2012, unpublished data)...
