Abstract

The Roles of AcyII Gene Mutations for Production of Antibiotics Derived From CephalosporinSemisynthetic antibiotics cephalosporins are widely used to treat infectious diseases, especially those caused by gram-negative bacteria. Various types of semisynthetic antibiotics could be synthesized using 7-aminocephalosporanic acid (7-ACA) as the main raw material. 7-ACA is obtained by conversion of cephalosporin C, either chemically or enzymatically. Converting cephalosporin C to 7-ACA enzymatically in one step involves the cephalosporin acylase enzyme. Currently, all of cefalosporin acylase enzymes produced by wild-type microbes have only high activity on glutaryl-7-ACA as the main substrate. Genetic engineering of the encoding gene of cefalosporin acylase is required to obtain recombinant enzyme having high activity on cephalosporin C. In this paper, the engineering attempts made on acyII gene from Pseudomonas SE83 using directed mutagenesis, error prone PCR, and structural modeling are described. Keywords: AcyII gene, cephalosporin, cephalosporin C acylase, enzyme activity, mutation ABSTRAKAntibiotik sefalosporin semisintetik banyak digunakan untuk mengatasi penyakit infeksi, khususnya yang ditimbulkan oleh bakteri gram negatif. Berbagai jenis antibiotik semisintetk dapat disintesis menggunakan senyawa asam 7-aminosefalosporanat (7-ACA) sebagai bahan baku utamanya. Senyawa 7-ACA diperoleh melalui konversi sefalosporin C, baik yang dilakukan secara kimiawi maupun enzimatis. Konversi sefalosporin C menjadi 7-ACA secara enzimatis dalam satu langkah melibatkan enzim sefalosporin asilase. Hingga saat ini, seluruh enzim sefalosporin asilase yang dihasilkan oleh mikroba wild type hanya mempunyai aktifitas yang tinggi terhadap glutaryl-7-ACA. Rekayasa genetik terhadap gen pengkode enzim sefalosporin asilase diperlukan untuk memperoleh enzim rekombinan yang mempunyai aktifitas tinggi terhadap substrat sefalosporin C. Dalam ulasan ini diuraikan upaya-upaya rekayasa yang telah dilakukan terhadap gen acyII dari Pseudomonas SE83 menggunakan teknik mutasi terarah, error prone PCR, dan pemodelan struktur.Kata kunci: Aktivitas enzim, gen acyII, mutasi, sefalosporin, sefalosporin C asilase Received: 14September 2017    Accepted: 19 December 2017     Published: 30 December 2017    Received: 14September 2017                Accepted: 19 December 2017           Published: 30 December 2017

Abstract

D-amino acid oxidase (DAAO) is a flavin adenine dinucleotide-containing enzyme that catalyzes the oxidative deamination of amino acid D-isomers with high stereospecificity, which results in α-keto acids, ammonia and hydrogen peroxide. Having high stereospecificity, DAAO is used in a variety of applications such as drug, biocatalyst, biosensor and preparation of transgenic plants. DAAO is widespread in nature, found in microorganisms to mammals. Microbial DAAO is considered more important than mammalian DAAO for biotechnology application. DAAO production in submerged fermentation is influenced by several factors, such as carbon source, nitrogen source, inducer, dissolve oxygen, temperature and pH. The influence of those factors on DAAO production by microbial origin, DAAO production by microbial recombinant, and its application in biotechnology are discussed in this review.Keywords: Enzyme, DAAO, D-amino acid, production, application ABSTRAKEnzim D-asam amino oksidase (DAAO) merupakan enzim yang mengandung Flavin Adenine Dinucleotide yang bekerja mengkatalisis reaksi oksidasi deaminasi D-asam amino dengan stereospesifisitas yang tinggi menghasilkan α-asam keto, amonia dan hidrogen peroksida. Karena mempunyai karakteristik sreteospesifisitas yang tinggi, enzim DAAO banyak digunakan untuk berbagai aplikasi seperti obat, biokatalis, biosensor dan penyiapan tanaman transgenik. Enzim ini dapat dihasilkan oleh organisme mulai dari bakteri hingga mamalia, namun untuk aplikasi dibidang bioteknologi, enzim DAAO yang berasal dari mikroorganisme dipandang lebih penting dari pada yang berasal dari mamalia. Produksi enzim dari DAAO dari mikroorganisme dalam kultur cair dipengaruhi oleh beberapa faktor seperti sumber karbon, nitrogen, senyawa penginduksi, oksigen terlarut, temperatur dan pH medium. Pengaruh dari faktor-faktor tersebut terhadap produksi enzim DAAO, produksi enzim DAAO menggunakan mikroba rekombinan serta aplikasinya dalam bidang bioteknologi dibahas dalam tinjauan.Kata Kunci: Enzim, DAAO, D-asam amino, produksi, aplikasi

Abstract

The sustainability of global palm oil production faces significant threats from a range of diseases and infections affecting palm oil crops. This study presents a comprehensive bibliometric analysis to map the scientific landscape and evolution of research related to palm oil diseases over the past decade. Using data from the Scopus database, 366 relevant documents were analyzed using R and VOSviewer to uncover trends in publication volume, citation impact, prolific authors, country contributions, and keyword co-occurrence networks. The findings reveal a strong research concentration on G. boninense, highlighting its critical role as a persistent pathogen in oil palm plantations. Emerging themes, such as bioactive compound research, comparative biology, and plant–microbiome interactions, reflect the growing interdisciplinary interest in sustainable disease management. This study identified key research gaps and proposed future directions, including molecular breeding, biocontrol strategies, and valorization of bioactive compounds from oil palm by-products. The results offer strategic insights to guide future scientific inquiry and inform sustainable solutions for global palm oil production.
