|CATERING PROPOSAL TEMPLATE FREE||5 days ago · It is widely assumed that today’s large and complex proteins emerged from much shorter and simpler polypeptides. Yet the nature of these early precursors remains enigmatic. We describe polypeptides that contain one of the earliest protein motifs, a phosphate-binding loop, or P-loop, embedded in a single beta-alpha element. These simple P-loop polypeptides show intriguing . VEGAN / PLANT-BASED PROTEINS & SUPERFOODS. Plants provide some of the best concentrated nutrition. Sunwarrior creates clean vegan proteins and supplements, meal replacements, mineral complexes, immune boosters, and greens. Each are rich in absorbable nutrients from vitamins, minerals, enzymes, probiotics, and antioxidants to amino acids. 2 days ago · For an enzyme and substrate to bind they have to fit together physically. Each enzyme has a region on its surface called the active site (Figure 3). This is a cleft in the protein surface where the substrate binds. It has a shape that fits the substrate like a glove fits a hand or a lock fits a key.|

An enzyme will only work on one substrate - it is substrate specific. Enzymes and substrates collide to form enzyme-substrate complexes.
The substrates are broken down or in some cases built up. The products are released. The enzyme is free to act again.
It explains why each enzyme will only work on one substrate. For example, the active site of amylase is only complementary to starch and will therefore only break down starch, not protein or fat.]
