What is glyenzy?

Glycan biosynthesis as a traceable enzyme graph, now including sulfation and gaps it can bridge.

glyenzy infers which enzymes could have produced a glycan and traces biosynthetic routes to it, backed by curated per-enzyme rules for human glycosyltransferases and, since 0.7.0, twelve sulfotransferases. Biosynthesis functions return typed network objects that keep their igraph interface while supporting layered DAG plots with glycan nodes and labelled enzyme edges. Where no concrete enzyme covers a step, bounded virtual transitions bridge the gap and are marked so users can see which edges are inferred rather than enzymatic.

What is StreamCatTools?

StreamCatTools is quietly moving off web services and onto cloud-native GeoParquet

StreamCatTools is the R client for the US EPA's StreamCat and LakeCat watershed metrics datasets. Through 2025 it worked almost entirely against the StreamCat web API, and much of its release history is about making those HTTP calls survive real conditions — POST bodies for long COMID lists, tryCatch around service outages, tests that skip when the service is down. 0.11.0 in May 2026 introduces a different data path.

Glycan biosynthesis as a traceable enzyme graph, now including sulfation and gaps it can bridge.

◆ Current state

glyenzy infers which enzymes could have produced a glycan and traces biosynthetic routes to it, backed by curated per-enzyme rules for human glycosyltransferases and, since 0.7.0, twelve sulfotransferases. Biosynthesis functions return typed network objects that keep their igraph interface while supporting layered DAG plots with glycan nodes and labelled enzyme edges. Where no concrete enzyme covers a step, bounded virtual transitions bridge the gap and are marked so users can see which edges are inferred rather than enzymatic.

◆ Where it's heading

Two kinds of release alternate here. One is enzyme curation, a steady stream of rule corrections for the FUT, MAN1A and MGAT families and removals where an enzyme turned out to act only on glycolipids, which is the unglamorous accuracy work a rule-based inference engine lives on. The other is turning biosynthesis output into a first-class object: paths became networks, networks became typed with plotting support, and targets became a marked vertex attribute. The package moves in lockstep with its siblings, pinning glyrepr 0.13.0 and glymotif 0.17.0 as those refreshed their data and matching APIs, and the latest release already speaks glydraw 0.8.0's orientation values.

◆ Prediction

The paucimannose N-glycan support dropped in 0.7.0 is the obvious loose end, with users told to stay on 0.6.3, so a reinstated implementation is a plausible next move. Beyond that the virtual-step machinery is new enough that its heuristics, particularly the inferred step limits added in 0.8.1, should keep being tuned.

StreamCatTools is quietly moving off web services and onto cloud-native GeoParquet

◆ Current state

StreamCatTools is the R client for the US EPA's StreamCat and LakeCat watershed metrics datasets. Through 2025 it worked almost entirely against the StreamCat web API, and much of its release history is about making those HTTP calls survive real conditions — POST bodies for long COMID lists, tryCatch around service outages, tests that skip when the service is down. 0.11.0 in May 2026 introduces a different data path.

◆ Where it's heading

The newest release adds lc_get_watershed(), which returns a lake watershed as an sf feature by reading an S3-hosted, HUC2-partitioned GeoParquet dataset with DuckDB, optional HUC2 filtering, retries and multi-threading. That is a materially different access model from the web service the rest of the package uses. Alongside it, 0.10.0 added National Nutrient Inventory access and nitrogen/phosphorus budget plotting, extending the package past retrieval into presentation.

◆ Prediction

If the GeoParquet path proves faster and more reliable than the web service, migrating more retrieval functions onto it is the obvious next move. The entries do not say whether EPA intends to publish the full metric catalogue in that format.
