“…Additionally, we also identified a rpulFKz1 homolog from Stomolophus meleagris Agassiz, 1860, and previous studies on the blue pigments of Stomolophus spp. have found similar spectroscopic and physicochemical properties to rpulFKz1 and Cassio Blue (Lugo-Magaña et al, 2018;Martínez-Pérez et al, 2020). Therefore, we hypothesize that the eight proteins identified as rpulFKz1 homologs are also pigment precursors.…”

Rhizostomins: A Novel Pigment Family From Rhizostome Jellyfish (Cnidaria, Scyphozoa)

Many pigments, such as melanins, are widely distributed throughout the animal kingdom. Others have arisen as novelties in particular lineages, for example, the Green Fluorescent Protein (GFP) found in cnidarians. While GFPs, widely used as fluorescent tags in biomedical research, are the most famous cnidarian example, other novel proteins have also been identified within this phylum. A blue protein that contains a Kringle (KR) domain inserted within a Frizzled cysteine-rich domain (Fz-CRD) was previously described from the jellyfish Rhizostoma pulmo (named rpulFKz1), however little is known about this pigment’s evolution or distribution among cnidarians. We performed a systematic search for homologs of this protein in published genomes and transcriptomes of 93 cnidarians. Phylogenetic analyses revealed eight predicted proteins that possess both domains in the same arrangement and that fall within the same clade as rpulFKz1. The sequence of one of these proteins contains motifs that match sequenced peptides of Cassio Blue, the blue pigment from Cassiopea xamachana. Another one of these proteins belongs to Stomolophus meleagris, and chemical studies on blue pigments that may occur in this genus have shown similarities to rpulFKz1 and Cassio Blue. Therefore, we hypothesize that the eight rpulFKz1 homologs identified are also pigment precursors. All precursors identified were exclusive to jellyfish in the order Rhizostomeae, so we herein name this new pigment family “rhizostomins.” Not all rhizostomes analyzed are blue, however, so these rhizostomin proteins may also be responsible for other colors, or perform other biochemical and biophysical roles. Previous studies have hypothesized that cnidarian pigments are photoprotective, and this study serves as basis for future investigations not only on the function of rhizostomins, but also on potential biotechnological applications for these proteins.

“…Meanwhile, the chemical characteristics of these blue pigments have been well studied in reported Rhizostomeae jellyfish [10][11][12][13]15]. As the scarce pigment in nature, blue pigments have great potential in aquaculture, food, health industries, and cosmetics [16,17]. Therefore, investigating blue pigments of R. esculentum is not only beneficial for revealing the blue color formation but also for further exploitation and utilization of R. esculentum resources.…”

Rhopilema esculentum is widely cultured in Chinese coastal regions and has thousand years of consumption history in China. Despite R. esculentum owns multiple colors (mainly ochre and blue) in aquaculture ponds, little is known about the pigments and color formation. This study identified and verified the blue pigment of R. esculentum. Results showed that the blue pigment of R. esculentum has 262 amino acids with 54.96% identity to the blue pigment protein precursor of Rhizostoma pulmo. The blue pigment of R. esculentum has Kringle and Frizzled domains, which is in accordance with rhizostomins characteristics. Compared to ochre R. esculentum, the expression level of blue pigment increased 3.49-fold in blue R. esculentum. In addition, overexpression of the blue pigment in Rhodosporidium toruloides made transformant cells blue under blue light excitation. Our findings provide knowledge for the blue color formation of R. esculentum and will benefit the color selection of R. esculentum with excellent traits.
