A vital enzyme for sperm formation could possibly be a goal for treating male infertility — ScienceDaily

Whereas a few of our physique’s cells divide in a matter of hours, the method of constructing sperm, meiosis, alone takes about 14 days from begin to end. And totally six of these days are spent within the stage often known as the pachytene, when pairs of chromosomes from a person’s mom and father align and join. “This stage is basically necessary, as a result of the pair must be aligned for the alternate of genetic materials between these two chromosomes,” says P. Jeremy Wang, a biologist in Penn’s College…

Bacterial enzyme might grow to be a brand new goal for antibiotics — ScienceDaily

MIT and Harvard College chemists have found the construction of an uncommon bacterial enzyme that may break down an amino acid present in collagen, which is essentially the most considerable protein within the human physique. The enzyme, often called hydroxy-L-proline dehydratase (HypD), has been present in a couple of hundred species of micro organism that reside within the human intestine, together with Clostridioides difficile. The enzyme performs a novel chemical response that dismantles hydroxy-L-proline, the molecule that offers collagen its powerful, triple-helix construction. Now that researchers know the construction of…
