| The human placenta, characterized by the processes of passive transport and facilitated diffusion, contains numerous active transport proteins. |
| This messenger in turn activates a so-called kinase, an enzyme that attaches phosphate groups to other proteins. |
| The ability of DNA polymerases to replicate DNA requires a number of additional accessory proteins. |
| There are three types of PPARs, which are proteins that control how the body absorbs, stores, and distributes fat. |
| In addition to histones, some HATs can acetylate non-histone proteins, suggesting multiple roles for these enzymes. |
| Therefore, it is questionable whether functional proteins are expressed from this region. |
