Biosynthesis and regulation of anthocyanin pathway genes.

Anthocyanins are the phenolic compounds responsible for coloring pigments in fruits and vegetables. Anthocyanins offer a
wide range of health benefits to human health. Their scope has expanded dramatically in the past decade, making anthocyanin
control, influx, and outflow regulation fascinating for many researchers. The main culprit is anthocyanin stability and
concentration form, which demands novel ways because these are critical in the food industry. This review aims to examine
anthocyanin synthesis via triggering transcription genes that code for anthocyanin-producing enzymes. The balance between
production and breakdown determines anthocyanin accumulation. Thus, increasing the anthocyanin content in food requires
the stability of molecules in the vacuolar lumen, the pigment fading process, and a better understanding of the mechanism.
The promising option is biosynthesis by metabolically engineered microorganisms with a lot of success. This study aims to
look into and evaluate the existing literature on anthocyanin production, namely the biosynthesis of anthocyanin pathway
genes, production by microbial cell factories, and the regulatory factors that can modulate the production of anthocyanins.
Understanding these mechanisms will provide new biotechnological approaches.
