The site contains the three active centers found in the naturally occurring enzyme: an organic molecule called phenol, an iron atom and a copper atom. Working together, these three centers provide the four electro...

Newly identified strains of Chlamydia trachomatis could produce new diseases

...ds. Bacterial infection develops as the eyelashes scratch the surface of the eye, which eventually heals by scarring, resulting in blindness. Previously, the organism was identified using a single gene, ompA, and the protein encoded by that gene, MOMP. In this study, the clinical strains, which are sampl...

Whole-genome study at Johns Hopkins reveals a new gene associated with abnormal heart rhythm

... took the unconventional approach of starting from scratch and not looking at genes already known or suspected to be involved in heart rhythm. "Studying individual genes is not going to open new areas of research," says Chakravarti. "Using a whole-genome approach allows us to find new targets that we never ...

Researchers solve mystery of how nuclear pores duplicate before cell division

...rmed but also to demonstrate that they formed from scratch without the help of already existing pores." In another experiment, the group used four-dimensional confocal microscopy to follow the formation in cultured human cells of a single pore that had been labeled with a fluorescent tag. If the nuclear por...

As a further test of the durability of the coating, the researchers also immersed coated components in an exfoliation solution consisting of nitric acid and chloride with v...

The link between fasting and acute attacks of porphyria

...to jump-start the process of creating glucose from scratch in the liver. However, PGC-1a also regulates the activity of an enzyme called ALAS-1, the first key enzyme in the heme production pathway. The higher levels of PGC-1a produce higher levels of ALAS-1, leading to a toxic buildup of precursor heme molec...
