isPermaLink="false">http://biology-today.com/?p=1928</guid> <description><![CDATA[Allosteric enzymes have, in addition to an active site, another stereo-specific site to which an effector or modulator molecule can bind. When it does, the shape of the active site is altered so that it can or cannot bind substrate (allosteric stimulation or inhibition respectively). In this way the enzyme can be part of a [...]]]></description> <wfw:commentRss>http://biology-today.com/general-zoology/vertebrate-zoology/what-is-allosteric-enzyme/feed/</wfw:commentRss> <slash:comments>0</slash:comments> </item> <item><title>Chemical Nature and Function of enzyme</title><link>http://biology-today.com/general-zoology/vertebrate-zoology/chemical-nature-and-function-of-enzyme/</link> <comments>http://biology-today.com/general-zoology/vertebrate-zoology/chemical-nature-and-function-of-enzyme/#comments</comments> <pubDate>Tue, 13 Dec 2011 13:05:21 +0000</pubDate> <dc:creator>Zoology</dc:creator> <category><![CDATA[Vertebrate Zoology]]></category> <category><![CDATA[Chemical structure of enzyme]]></category> <category><![CDATA[enzyme]]></category> <category><![CDATA[Function of enzyme]]></category><guid
isPermaLink="false">http://biology-today.com/?p=1918</guid> <description><![CDATA[All enzymes are proteins. An enzyme molecule may contain one or more polypeptide chains. The sequence of amino acids within the polypeptide chains is characteristic for each enzyme, and is believed to determine the unique three-dimensional conformation in which the chains are folded.  This conformation, which is necessary for the activity of the enzyme, is [...]]]></description> <wfw:commentRss>http://biology-today.com/general-zoology/vertebrate-zoology/chemical-nature-and-function-of-enzyme/feed/</wfw:commentRss> <slash:comments>0</slash:comments> </item> <item><title>Mention the exception of enzyme&#8217;s protein nature</title><link>http://biology-today.com/physiology/mention-the-exception-of-enzymes-protein-nature/</link> <comments>http://biology-today.com/physiology/mention-the-exception-of-enzymes-protein-nature/#comments</comments> <pubDate>Sun, 04 Sep 2011 03:27:26 +0000</pubDate> <dc:creator>Zoology</dc:creator> <category><![CDATA[Physiology]]></category> <category><![CDATA[enzyme]]></category> <category><![CDATA[protein nature of enzyme]]></category><guid
isPermaLink="false">http://biology-today.com/?p=1770</guid> <description><![CDATA[Most enzymes are of protein nature. But there are some exceptions. For example, a few RNA molecules show some catalytic action. These RNA molecules are known as ribozymes. These are actually ribonucleoprotein particles, i.e., made up of protein and RNA, but only RNA portion shows catalytic activity. Example- RNase P in E. coli acts as [...]]]></description> <wfw:commentRss>http://biology-today.com/physiology/mention-the-exception-of-enzymes-protein-nature/feed/</wfw:commentRss> <slash:comments>0</slash:comments> </item> <item><title>What are enzyme, substrate &amp; product?</title><link>http://biology-today.com/physiology/what-are-enzyme-substrate-product/</link> <comments>http://biology-today.com/physiology/what-are-enzyme-substrate-product/#comments</comments> <pubDate>Sun, 04 Sep 2011 03:23:58 +0000</pubDate> <dc:creator>Zoology</dc:creator> <category><![CDATA[Physiology]]></category> <category><![CDATA[enzyme]]></category> <category><![CDATA[product]]></category> <category><![CDATA[substrate]]></category><guid
isPermaLink="false">http://biology-today.com/?p=1764</guid> <description><![CDATA[An enzyme is a biocatalyst that increases the rate of chemical reaction without being changed in the overall process. Enzymes change covalent bonds of some biochemical substances and transform that substance to a new substance. The substance that undergoes covalent modification is known as substrate of that enzyme and the newly produced substance is known [...]]]></description> <wfw:commentRss>http://biology-today.com/physiology/what-are-enzyme-substrate-product/feed/</wfw:commentRss> <slash:comments>0</slash:comments> </item> <item><title>What to you mean by stereospecifity of enzyme?</title><link>http://biology-today.com/biochemistry/what-to-you-mean-by-stereospecifity-of-enzyme/</link> <comments>http://biology-today.com/biochemistry/what-to-you-mean-by-stereospecifity-of-enzyme/#comments</comments> <pubDate>Thu, 19 Mar 2009 03:48:21 +0000</pubDate> <dc:creator>Zoology</dc:creator> <category><![CDATA[Biochemistry]]></category> <category><![CDATA[enzyme]]></category> <category><![CDATA[stereospecifity]]></category><guid

However, it is only one of the isomers which acts as a substrate for enzyme action eg.; for hydrolysis of poplypeptides at D- and L- amino acids- there are two types of enzyme needed which will act on D- and L- isomers of amino acids.

Like all catalysts enzymes have the property of reappearing essentially unchanged at the end of a reaction. Two striking features about enzymes make them best catalysts known. These are their effectiveness and their specificity.]]></description> <wfw:commentRss>http://biology-today.com/general-zoology/what-is-an-enzyme/feed/</wfw:commentRss> <slash:comments>0</slash:comments> </item> </channel> </rss>
