  peptide bonds to give linear homo-oligopeptides, hetero-dipeptides, and cyclic dipeptides using cost-effective substrates in a one-pot reaction. Aminolysin-A can recognize several C-terminal-modified amino acids, including the L- and D-forms, as acyl donors as well as free amines, including amino acids and puromycin aminonucleoside, as acyl acceptors. The absence of amino acid esters prevents the formation

  新S9系列的氨肽酶从嗜热放线菌衍生Acidothermus了解纤维素被催化丝氨酸的定点突变克隆和工程化到transaminopeptidase 491到半胱氨酸。经过工程改造的生物催化剂，称为氨基溶素A，可以在一锅反应中使用经济高效的底物来催化肽键的形成，从而生成线性同型寡肽，杂二肽和环状二肽。氨基溶素A可以识别多个C末端修饰的氨基酸（包括L-和D-形式）作为酰基供体，以及游离胺（包括氨基酸和嘌呤霉素氨基核苷）作为酰基受体。氨基酸酯的缺乏阻止了肽的形成。因此，反应机理涉及氨解而不是水解的逆反应。氨基溶素系统将是通过简单方法制备结构多样的肽模拟物的有益工具。

  The present invention relates to a probe compound that can comprise any substrate or metabolite of an enzymatic reaction in addition to an indicator component, such as, for example, a fluorescence dye, or the like. Moreover, the present invention relates to means for detecting enzymes in form of an array, which comprises any number of probe compounds of the invention which each comprise a different metabolite of interconnected metabolites representing the central pathways in all forms of life. Moreover, the present invention relates to a method for detecting enzymes involving the application of cell extracts or the like to the array of the invention which leads to reproducible enzymatic reactions with the substrates. These specific enzymatic reactions trigger the indicator (e.g. a fluorescence signal) and bind the enzymes to the respective cognate substrates. Moreover, the invention relates to means for isolating enzymes in form of nanoparticles coated with the probe compound of the invention. The immobilisation of the cognate substrates or metabolites on the surface of nanoparticles by means of the probe compounds allows capturing and isolating the respective enzyme, e.g. for subsequent sequencing.

  Methods and systems for increasing the stability of a nucleic acid template that encodes a protein of interest in a cell free translation system or a ribosomal display reaction system are described. In some embodiments, the nucleic acid template is an RNA or mRNA. The stability of the RNA template is increased by adding the bacteriophage lambda protein Gam to the cell free extract used in the translation system. The addition of Gam protein increases the longevity of the reaction system, thereby increasing the efficiency of the ribosomal display reaction system.
