Biosynthesis involving multi-enzymatic reactions is usually an efficient and economic method to produce plentiful important molecules. To increase the product yield in biosynthesis, the involved enzymes can be immobilized to carriers for enhancing enzyme stability, increasing synthesis efficiency and improving enzyme recyclability. Hydrogels with three-dimensional porous structures and versatile functional groups are promising carriers for enzyme immobilization. Herein, we review the recent advances of the hydrogel-based multi-enzymatic system for biosynthesis. First, we introduce the strategies of enzyme immobilization in hydrogel, including the pros and cons of the strategies. Then we overview the recent applications of the multi-enzymatic system for biosynthesis, including cell-free protein synthesis (CFPS) and non-protein synthesis, especially high value-added molecules. In the last section, we discuss the future perspective of the hydrogel-based multi-enzymatic system for biosynthesis.

Endometriosis, the growth of endometrial-like tissue outside the uterus, causes chronic pain and infertility in 10 % of reproductive-aged women worldwide. Unfortunately, no permanent cure exists, and current medical and surgical treatments offer only temporary relief. Endometriosis is a chronic inflammatory disease characterized by immune system dysfunction.

Organophosphate pesticides (OPs) are causing non-selective inhibition in enzymatic bioreceptors, thus the enzymatic-inhibition-based traditional assays are not suitable for their specific detection in food and environmental samples. Accordingly, a selective nanostructured electrochemical biosensing system was designed using six mutants of the esterase-2 (EST2 protein) enzymes from A. acidocaldarius to be exploited as targeting bio-receptors for the specific detection of OPs.

Article Synopsis
- * The study introduces engineered bifunctional fusion enzymes from purine nucleoside phosphorylase I (PNP I) and thymidine phosphorylase (TP), offering a more efficient one-pot synthesis method for nucleosides, as opposed to traditional multi-enzyme systems.
- * These fusion enzymes operate well at high temperatures (60-90 °C) and specific pH levels (6-8), demonstrating strong stability and successful catalysis for various nucleoside analogs, highlighting their potential in

Multi-enzymatic cascade reaction provides a new avenue for C─C coupling directly from CO under mild conditions. In this study, a new pathway with four enzymes including formate dehydrogenase (PaFDH), formaldehyde dehydrogenase (BmFADH), glycolaldehyde synthase (PpGALS), and alcohol dehydrogenase (GoADH) is developed for directly converting CO gas molecules to ethylene glycol (EG) in vitro. A rhodium-based NADH regeneration electrode is constructed to continuously provide the proton and electron of this multi-enzymatic cascade reaction.

Functional metagenomics enables the study of unexplored bacterial diversity, gene families, and pathways essential to microbial communities. However, discovering biological insights with these data is impeded by the scarcity of quality annotations. Here, we use a co-occurrence-based analysis of predicted microbial protein functions to uncover pathways in genomic and metagenomic biological systems.
