| Photosynthesis is a process used by plants and other organisms to convert the light energy captured from the sun into chemical energy that can be used to fuel the organism's activities. During this process, the obligation of the Calvin cycle is to fix carbon. In eukaryotes, the reactions of Calvin cycle are catalyzed by 11 enzymes, while, in prokaryotes, this number has decreased into 10. The c... more |

The new genes are not popped out in a random puff from nature. On the contrary, their débuts are the... more |

| Protein ubiquitination regulates multiple cancer-related cellular processes, including cell cycle. Typically, it is sequentially mediated by three enzymes: ubiquitin-activating enzyme (E1), ubiquitin-conjugating enzyme (E2), and ubiquitin ligase (E3) that controls substrate specificity. During which, ubiquitin E3 ligases are considered to be the next wave of molecules for targeted therapy. Howe... more |
