The polyketide synthase (PKS)-like protein TerB, consisting of inactive dehydratase, inactive C-methyltransferase, and functional ketoreductase domains collaborates with the iterative non reducing PKS TerA to produce 6-hydroxymellein, a key pathway intermediate during the biosynthesis of various fungal natural products. The catalytically inactive dehydratase domain of TerB appears to mediate productive interactions with TerA, demonstrating a new mode of trans-interaction between iterative PKS components.

Article Synopsis
- β-Carbonic anhydrases (β-CAs) are zinc metalloenzymes that convert carbon dioxide into bicarbonate and are found in various bacteria, playing crucial roles in their growth and survival.
- β-CAs are classified into two subgroups based on their zinc ion's fourth ligand; class I has a hydroxide ion, while class II features an Asp residue, leading to an inactive form below pH 8.
- A specific Asp-Arg dyad regulates the catalytic activity by controlling the active site's opening and closing, and there are additional sites that bind bicarbonate, contributing to the enzyme's functionality.

Two novel series of hydrazinyl-based benzenesulfonamides 9a-j and 10a-j were designed and synthesized using SLC-0111 as the lead molecule. The newly synthesized compounds were evaluated for their inhibitory activity against four different human carbonic anhydrase (hCA) isoforms I, II, IX, and XII. Both the series reported here were practically inactive against the off-target isozyme hCA I.

Human carbonic anhydrases (hCAs) play a central role in various physiological processes in the human body. HCAs catalyze the reversible hydration of CO into HCO, and hence maintains the fluid and pH balance. Overexpression of CA II is associated with diseases, such as glaucoma, and epilepsy.
