Over the past 15 years, we have registered an immense progress in the field of biosynthesis of secondary metabolites from marine macro- and microorganisms. The main reason for this success is directly related to the use of new genetic tools in natural products research allowing to look at genes and their function in samples obtained from marine.

The mixed nonribosomal peptide synthase/polyketide synthase biosynthetic pathways for the natural products curacin and cryptophycin are explored as case studies in enzymatic diversity. The expanding class of atypical trans at natural products is also discussed. Emerging tools for characterizing these enzymes are also explored.
Hydrazine, hydrazone and hydrazide derivatives are nitrogen-nitrogen bond containing compounds. Such molecules are relatively scarce in nature and have been isolated from plants, marine organisms and microorganisms. These compounds exhibit remarkable structural diversity and relevant biological activities.
Fucoxanthin and its derivatives are the main light-harvesting pigments in the photosynthetic apparatus of many chromalveolate algae and represent the most abundant carotenoids in the world’s oceans, thus being major facilitators of marine primary production. A central step in fucoxanthin biosynthesis that has been elusive so far is the conversion of violaxanthin to neoxanthin.
Biosynthetic systems are largely targeted from marine microbes, which harbor promising natural product compounds such as the potent anticancer agents salinosporamide a and didemnin, the polyketide antibiotics taromycin and marinopyrrole, and the neurotoxins domoic acid and kainic acid.
Here, we review the biosynthesis of fm, which includes a recent breakthrough to find a missing link in the biosynthetic pathway that had been a mystery for a quarter-century. In addition, we describe the genome mining of phosphonate natural products using the biosynthetic gene encoding an enzyme that catalyzes c–p bond formation.
Survey the biosynthetic pathways of cyanobacteria isolated from freshwater, marine and terrestrial habitats. We especially empha-size modular nonribosomal peptide synthetase (nrps) and polyketide synthase (pks) pathways and highlight the unique enzyme mechanisms that were elucidated or can be anticipated for the individual products.

Cytochalasans are a large family of well-studied cytotoxic molecules isolated from fungi. Investigation into the organic extract of the marine-derived fungal strain aspergillus flavipes cnl-338.
5 in view of his well-documented interest in linking marine natural products to their true bio-logical roles, it seems highly appropriate to review current knowledge on the chemistry and biosynthesis of this intriguing class of marine natural product, and to place this chemistry in a biological context.
To date, the function of most marine natural product biosynthetic genes have been deduced through bioinformatic analysis. At the protein level, little has been achieved because there is so little knowledge of biosynthetic proteins in general and even less so from members of complex marine environments.
