Students have asked these similar questions

The beta-lactamase hydrolyzes the lactam-ring in penicillin. Describe the mechanism of hydrolysis, insuring to include the involvement of S, D, & K in the reaction sequence. Please help

To map the active site of beta-lactamase, the enzyme was hydrolyzed with trypsin to yield a hexapeptide (P1) with the following amino acids. Glu, Lys, Leu, Phe, Met, and Ser. Treatment of P1 with phenyl isothiocyanate yielded a PTH derivative of phenylalanine and a peptide (P2). Treatment of P1 with cyanogenbromide gave an acidic tetrapeptide (P3) and a dipeptide (P4).Treatment of P2 with 1-fluoro-2,4-dinitrobenzene, followed by complete hydrolysis, yields N-2,4-dinitrophenyl-Glu. P1, P2, and P3 contain the active site serine. Why doesn't D in this hexapeptide not participate in the hydrolysis of the beta-lactam ring even though S, K, and D are involved in the catalyst?

It should be explained that whether the progesterone bind to a cell-surface receptor or does it enter the cell to carry out its function.

Concept introduction:

Hormones are chemical substances synthesized in small amounts by endocrine tissues and carried by blood stream to another tissue, where it acts as a messenger to regulate the function of the target tissue or organ.

There are three major classes of molecules which function as hormones in vertebrates and they are,

Amino acid derivatives: It is a derivative of an amino acid formed by the reaction at the side chain functional group, carboxylic acid group, and amino group or by the replacement of a hydrogen atom by heteroatom.

Polypeptides: Polypeptides are organic polymers having several amino acids attached to each other in a chain.

Steroid: Steroids are a type of organic compound having a molecular structure with four rings connected to each other. This type of hormone is soluble in lipids.

Follicle stimulating hormone (FSH) and luteinizing hormone (LH) are the two hormones involved in fertility which are produced by the pituitary gland.

Expert Solution

Explanation of Solution

Progesterone is responsible for the physiological changes in women at specific phases of their life starting in puberty. It is a steroid hormone produced in ovaries. Steroid hormones are lipid soluble and so it can enter cells.
