Abstract

The green seaweed Ulva lactuca is found in coastal areas. Potential bioactive peptides have a wide range of uses, including antibacterial, antifungal, antiviral, alpha-amylase inhibitory, antiamnestic, ACE inhibitory, immunomodulatory, anticancer, antioxidative, contracting, anti-inflammatory, and more. This study's major goal was to use in-silico methods to reveal the availability and abundance of putative bioactive peptides in the RuBisCO protein of Ulva lactuca seaweed. The protein sequence was obtained using the UniProtKB database. The peptide sequences were produced by using the BIOPEP-UWM enzyme activity tool. The peptides were ranked using PeptideRanker, and the toxicity profile was assessed using ToxinPred. For the first time, the current in-silico investigation depicts the pharmacological characteristics of Ulva lactuca by focusing on the RuBisCO protein. Numerous bioactive peptides with inhibitory activity against the angiotensin-I converting enzyme (ACE), dipeptidyl peptidase IV, antioxidant, dipeptidyl peptidase III, renin, antithrombotic, antiamnestic, α-glucosidase, anti-inflammatory, hypolipidemic activity, and ion flow regulation were produced by the in-silico proteolysis of rubisco using 18 proteases. Based on the cutoff score >0.75, pancreatic elastase liberated the most bioactive peptide sequences from the rubisco compared to other proteases. Additionally, PeptideRanker's findings showed that a number of di-, tri-, and/or polypeptides produced from the RuBisCO have a great deal of potential to be used as bioactive peptides. These studies open up new opportunities for these bioactive peptides in the fields of pharmacy, medicine, the food sector, and marine biotechnology.

  • Several algal peptides exert anti-obesity effects through activation of AMPK, including peptides derived from Limnospira platensis, Auxenochlorella pyrenoidosa, and Ulva lactuca.

    “Several algal peptides have been identified to exert anti-obesity effects through the activation of AMP-activated protein kinase (AMPK). Notably, peptides derived from Limnospira platensis, Auxenochlorella pyrenoidosa, and the macroalgae Ulva lactuca have demonstrated such activity [115,119].”

    From Navigating the potential of algal peptides: health effects, market applications, and scientific challenges (2026) · cites this paper as [119]

    Section 3.2 and the discussion following Table 4 (page unavailable) report an in-silico prediction of a hypolipidemic peptide from Ulva lactuca that activates AMPK. They do not demonstrate an anti-obesity effect; this paper also does not provide evidence for the other two algae named in the citing sentence. (LLM, conf=0.89)

  • In silico-directed approaches have gained increasing popularity in recent studies of algal proteins (e.g. Limnospira platensis, Chlorella vulgaris, and Ulva lactuca) to guide discovery faster and maximize specificity of peptide selection.

    “Such in silico-directed approaches have gained increasing popularity in recent studies of algal proteins (e.g. Limnospira platensis, Chlorella vulgaris, and Ulva lactuca) to guide the discovery process faster and maximize the specificity of peptide selection [119,214,215].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
