Abstract
Lipase B from Candida antarctica (CALB) is an important biocatalyst with many potential applications. However, original CALB is usually with lower enzyme activity and also costly to produce from Candida antarctica; hence, it is often necessary to prepare recombinant CALB through gene heterologous expression. In this research, seven promoters and five signal peptides were compared respectively for expressing codon-optimized CALB in Pichia pastoris, and then recombinant P. pastoris containing 3 copies of calb gene were obtained by screening with high concentrations of antibiotics under the condition of the optimal combination. In a 1.3-L bioreactor, the maximum CALB activity and total protein content reached 444.46 ± 18.81 U/mL and 5.41 ± 0.1 g/L, respectively, after about 9 days of incubation in FM22 medium, which were 34 times and 20 times higher than the initial strains, respectively. In addition, the obtained CALB was used to catalyze the transesterification of acidified gutter oil with methanol, suggesting a promising pathway to convert waste or low quality of bio-oil feedstocks with high amount of free fatty acids into biodiesel by using recombinant CALB as catalyst. The results can provide with a good reference for efficient expression of CALB and enhancing lipase production in P. pastoris. It is supposed to bring with new possibility for the bio-production of other valuable proteins.

Abstract
The non-conventional yeast Pichia pastoris (syn. Komagataella phaffii) has become a powerful eukaryotic expression platform for biopharmaceutical and biotechnological applications on both laboratory and industrial scales. Despite the fundamental role that artificial transcription factors (ATFs) play in the orthogonal control of gene expression in synthetic biology, a limited number of ATFs are available for P. pastoris. To establish orthogonal regulators for use in P. pastoris, we characterized ATFs derived from Arabidopsis TFs. The plant-derived ATFs contain the binding domain of TFs from the plant Arabidopsis thaliana, in combination with the activation domains of yeast GAL4 and plant EDLL and a synthetic promoter harboring the cognate cis-regulatory motifs. Chromosomally integrated ATFs and their binding sites (ATF/BSs) resulted in a wide spectrum of inducible transcriptional outputs in P. pastoris, ranging from as low as 1- to as high as ∼63-fold induction with only small growth defects. We demonstrated the application of ATF/BSs by generating P. pastoris cells that produce β-carotene. Notably, the productivity of β-carotene in P. pastoris was ∼4.8-fold higher than that in S. cerevisiae, reaching ∼59% of the β-carotene productivity obtained in a S. cerevisiae strain optimized for the production of the β-carotene precursor, farnesyl diphosphate, by rewiring the endogenous metabolic pathways using plant-derived ATF/BSs. Our data suggest that plant-derived regulators have a high degree of transferability from S. cerevisiae to P. pastoris. The plant-derived ATFs, together with their cognate binding sites, powerfully increase the repertoire of transcriptional regulatory modules for the tuning of protein expression levels required in metabolic engineering or synthetic biology in P. pastoris.

Abstract
The methylotrophic yeast Pichia pastoris (a.k.a. Komagataella phaffii) is one of the most commonly used hosts for industrial production of recombinant proteins. As a non-conventional yeast, P. pastoris has unique biological characteristics and its expression system has been well developed. With the advances in synthetic biology, more efforts have been devoted to developing P. pastoris into a chassis for the production of various high-value compounds, such as natural products. This review begins with the introduction of synthetic biology tools for the engineering of P. pastoris, including vectors, promoters, and terminators for heterologous gene expression as well as Clustered Regularly Interspaced Short Palindromic Repeats/CRISPR-associated System (CRISPR/Cas) for genome editing. This review is then followed by examples of the production of value-added natural products in metabolically engineered P. pastoris strains. Finally, challenges and outlooks in developing P. pastoris as a synthetic biology chassis are prospected.

Abstract
System-wide interactions in living cells and discovery of the diverse roles of transcriptional regulatory proteins that are mediator proteins with catalytic domains and regulatory subunits and transcription factors in the cellular pathways have become crucial for understanding the cellular response to environmental conditions. This review provides information for future metabolic engineering strategies through analyses on the highly interconnected regulatory networks in Saccharomyces cerevisiae and Pichia pastoris and identifying their components. We discuss the current knowledge on the carbon catabolite repression (CCR) mechanism, interconnecting regulatory system of the central metabolic pathways that regulate cell metabolism based on nutrient availability in the industrial yeasts. The regulatory proteins and their functions in the CCR signalling pathways in both yeasts are presented and discussed. We highlight the importance of metabolic signalling networks by signifying ways on how effective engineering strategies can be designed for generating novel regulatory circuits, furthermore to activate pathways that reconfigure the network architecture. We summarize the evidence that engineering of multilayer regulation is needed for directed evolution of the cellular network by putting the transcriptional control into a new perspective for the regulation of central carbon metabolism of the industrial yeasts; furthermore, we suggest research directions that may help to enhance production of recombinant products in the widely used, creatively engineered, but relatively less studied P. pastoris through de novo metabolic engineering strategies based on the discovery of components of signalling pathways in CCR metabolism. KEY POINTS: • Transcriptional regulation and control is the key phenomenon in the cellular processes. • Designing de novo metabolic engineering strategies depends on the discovery of signalling pathways in CCR metabolism. • Crosstalk between pathways occurs through essential parts of transcriptional machinery connected to specific catalytic domains. • In S. cerevisiae, a major part of CCR metabolism is controlled through Snf1 kinase, Glc7 phosphatase, and Srb10 kinase. • In P. pastoris, signalling pathways in CCR metabolism have not yet been clearly known yet. • Cellular regulations on the transcription of promoters are controlled with carbon sources.

Abstract
The methylotrophic yeast Pichia pastoris (Komagataella phaffii) is currently considered one of the most promising hosts for recombinant protein production (RPP) and metabolites due to the availability of several tools to efficiently regulate the recombinant expression, its ability to perform eukaryotic post-translational modifications and to secrete the product in the extracellular media. The challenge of improving the bioprocess efficiency can be faced from two main approaches: the strain engineering, which includes enhancements in the recombinant expression regulation as well as overcoming potential cell capacity bottlenecks; and the bioprocess engineering, focused on the development of rational-based efficient operational strategies. Understanding the effect of strain and operational improvements in bioprocess efficiency requires to attain a robust knowledge about the metabolic and physiological changes triggered into the cells. For this purpose, a number of studies have revealed chemostat cultures to provide a robust tool for accurate, reliable, and reproducible bioprocess characterization. It should involve the determination of key specific rates, productivities, and yields for different C and N sources, as well as optimizing media formulation and operating conditions. Furthermore, studies along the different levels of systems biology are usually performed also in chemostat cultures. Transcriptomic, proteomic and metabolic flux analysis, using different techniques like differential target gene expression, protein description and 13C-based metabolic flux analysis, are widely described as valued examples in the literature. In this scenario, the main advantage of a continuous operation relies on the quality of the homogeneous samples obtained under steady-state conditions, where both the metabolic and physiological status of the cells remain unaltered in an all-encompassing picture of the cell environment. This contribution aims to provide the state of the art of the different approaches that allow the design of rational strain and bioprocess engineering improvements in Pichia pastoris toward optimizing bioprocesses based on the results obtained in chemostat cultures. Interestingly, continuous cultivation is also currently emerging as an alternative operational mode in industrial biotechnology for implementing continuous process operations.

Abstract
Engineered promoters are key components in the cell-factory design, allowing precise and enhanced expression of genes. Promoters having exceptional strength are attractive candidates for designing metabolic engineering strategies for tailoring de novo production strategies that require directed evolution methods by engineering with de novo synthetic biology tools. Here, the custom-designed AOX1 hybrid-promoter architectures in coordination with targeted transcription factors are shown, transcriptionally rewired the expression over methanol-free substrate-utilization pathway(s) and converted methanol-dependent Pichia pastoris alcohol oxidase 1(AOX1) promoter (PAOX1 ) expression into a non-toxic carbon-source-regulated system. AOX1 promoter variants are engineered by replacing specified cis-regulatory DNA elements with synthetic Adr1, Cat8, and Aca2 cis-acting DNA elements for Mxr1, Cat8, and Aca1 binding, respectively. Applications of the engineered-promoters are validated for eGFP expression and extracellular human serum albumin production. The hybrid-promoter architecture designed with single Cat8 cis-acting DNA element deregulates the expression on ethanol. Compared with PAOX1 on methanol, the expression on ethanol is increased with i) PAOX1/Cat8-L3 (designed with single Cat8 cis-acting element) to 74%, ii) PAOX1/Adr1-L3/Cat8-L3 (designed with single- Cat8 and Adr1 cis-acting elements) to 85%, and for further consolidation of deregulated expression iii) PeAOX1 (designed with triplet- Cat8 and Adr1 cis-acting elements) 1.30-fold, at t = 20 h of batch cultivations.
