metacyc_to_ec_reference: MetaCyc Pathway to EC Number Mapping Dataset

In ggpicrust2: Make 'PICRUSt2' Output Analysis and Visualization Easier

MetaCyc Pathway to EC Number Mapping Dataset

Description

A reference dataset mapping MetaCyc pathway identifiers to their associated Enzyme Commission (EC) numbers. Used internally by ggpicrust2 for MetaCyc pathway analysis, enabling the mapping between EC-level functional predictions and MetaCyc pathways.

Usage

data("metacyc_to_ec_reference")

Format

A data frame with 575 observations and the following columns:

pathway

Character. MetaCyc pathway identifier (e.g., "1CMET2-PWY")

ec_numbers

Character. Semicolon-separated list of EC numbers associated with the pathway

Source

MetaCyc database (https://metacyc.org)

Examples

data("metacyc_to_ec_reference")
head(metacyc_to_ec_reference)

# Count EC numbers per pathway
ec_counts <- sapply(strsplit(metacyc_to_ec_reference$ec_numbers, ";"), length)
summary(ec_counts)
