Question

Figure 9.17 shows three posttranslational steps required to produce the sugar-regulating hormone insulin from the starting polypeptide product preproinsulin.

A research scientist is interested in producing human insulin in the bacterial species E. coli. Will the genetic code allow the production of human proteins from bacterial cells? Explain why or why not.

Accepted Answer

Hi, everybody. Here's our next problem. A TP dependent proteases frequently digest misfolded proteins and bacteria in new caros misfolded proteins are frequently tagged with a covalent attached small protein called choice A kinase B ubiquitin C insulin or D histone. So we're thinking about a tag for with co a covalent attached small protein that tags misfolded proteins. The answer we're looking for is choice B ubiquitin. When we look at our other answer, choices, aces transfer phosphate groups from high energy molecules, but that's not what we're looking for. So that's not our answer. Choice. And choice C insulin helps to regulate metabolism of various types of biological molecules. Probably most famously carbohydrates, but not what we're looking for. And finally, choice de histone is of course part of the nucleosome structure, those proteins that form the core of the beads on a string structure of nucleus, but again, not what we're looking for here. So again, misfolded proteins frequently tagged with choice B ubiquitin. See you in the next video.
