Beta-lactamases are enzymes produced by bacteria. Gram-positive bacteria can produce beta-lactamases. This type of bacteria takes up the crystal violet stain in gram staining.
different parts of an individual;s DNA are used to direct the synthesis of different protein in different types of cells
Alpha glucose and beta glucose with a beta 1 4 glycosidic linkage!
When beta receptors are stimulated, it decreases the heart rate to treat for low blood pressure.
beta galactosidase breaks onpg into galactose and ortho-nitrophenol which gives a yellow colour
Beta-lactamase inhibitors, protect the penicillin from bacterial enzymes that may destroy it before it can do its work.
A beta-lactamase is an enzyme produced by certain bacteria, which is responsible for their resistance to beta-lactam antibiotics.
Ampicillin class C beta lactamase
Beta-lactamases are enzymes produced by bacteria. Gram-positive bacteria can produce beta-lactamases. This type of bacteria takes up the crystal violet stain in gram staining.
Beta lactamase is an enzyme, which is produced by some bacteria. This enzyme brakes the beta lactum ring that is present in beta lactum antibiotics. You have four groups in beta-lactum antibiotics. They are penicillins, cephalosporins, monobactums and carbapenems. So you naturally have the enzymes penicillinase, cephalospoinase, monobactamase and carbapenamase. Whether they are one and the same enzyme or four different enzymes is not clear to the contributor and needs comment by expert in this field.
Some bacteria produce beta lactamase enzyme, this enzyme will break the beta lactam ring structure of certain antibiotics (penicillin, cephalexin for example) rendering them ineffective against the infection. If you add a beta lactamase inhibitor to a beta lactam antibiotic (i.e clavulanaic acid added to amoxicillin) it decreases the potential of the bacteria to inactivate the antibiotic.
If you are wondering what is the name of a drug that contains amoxicillin - one would be Augmentin. This is made of amoxicillin and clavulanate. Clavulanate is what is referred to as a 'beta lactamase inhibitor' and this allows amoxicillin to be effective against drug-resistant bacteria that produce beta lactamase. Words ending in -ase are generally enzymes that are going to break something down. The penicillin family of antibiotics are called 'beta lactams' due to their structure. Some bacteria have developed beta lactamase in order to break down these antibiotics, thereby becoming a drug-resistant bacteria.

It is beta-lactamase. This is a type of enzyme that is produced by bacteria that is resistant to certain antibiotics. These include Cephalosporinase and Penicillinase. These enzymes destroy Cephalosporins and Penicillins respectively.
cefixime and clavulanic acid can be used as a second line therapy where cefixime alone is not able to show it's bacteriocidal activity. Cefixime comes under beta lactum antibiotic category and gets degrade inpresence of beta lactumase enzyme, bacterias have developed resistance against cefixime by producing beta lactamase and ESBLs. Clavulanic acid is an irreversible inhibitor of beta lactamase enzyme and have mild antibiotic activity. when this combination is used, clavulanic acid inhibits beta lactamase enzyme and allow cefixime work as a bacteriocidal. the combination is very useful against cefixime resistant becteria. more research work is required to understand the further use of this combination and also to find out the superiority of this combination over Amoxi+Clav combination.

Co-amoxiclav is an approved British name for the combination antibiotic containing compounds such as amoxicillin trihydrate, a beta-lactam antibiotic, with potassium clavulanate, and a beta-lactamase inhibitor. The combination yields an antibiotic with an increased spectrum of action and restored efficacy against amoxicillin-resistant bacteria that produce beta-lactamase.
