Insights into Octopus maya cathepsins from metatranscriptome and genome: structure evolutionary relationships and functional role prediction in digestive processes.

ABSTRACT: Physiological response to feeding is crucial for various production factors such as feed catabolism and growth. Despite growing significance in red Octopus maya aquaculture, large-scale commercial production is limited by not sufficiently knowing their nutritional needs, especially their digestive physiology. Since this species is carnivorous, one of the main feeding aspects is directed to protein digestion, but its enzymatic digestive repertoire has not been studied yet at genomic and transcriptomic levels. This study searched for protease enzymes encoded in O. maya genome and expressed in the transcriptome, allowing an initial annotation of genes involved in protein catabolism; 117 amino acid sequences related to 'octopus digestive enzymes' were retrieved from 66 available-species' genom
