Statistical analysis of the Bacterial Carbohydrate Structure Data Base (BCSDB): Characteristics and diversity of bacterial carbohydrates in comparison with mammalian glycans

Table 3 Diversity of monosaccharides, basetypes and basic entities for various taxonomic groups.

Group	Monosaccharides	Basetypes	Basic entities
Mammalia	35	14	10 *
Bacteria	551	143	123
Actinobacteria	100	48	33
Bacilli	100	41	34
α-Proteobacteria	68	34	26
β-Proteobacteria	69	33	32
Enterobacteriales (γ-Proteobacteria)	243	76	65
other γ-Proteobacteria	203	70	76 **
δ/ε-Proteobacteria	52	35	32

The total number of different monosaccharides, basetypes, and basic entities are listed for each group in taxonomy Set 1 and Set 2. When counting in the combined databases, an occurrence threshold of 10 for mammals and 2 for bacteria was employed.
* The basic entity D-Fuc was excluded from Mammalia for reasons given in the text.
** In this case there are more basic entities compared to basetypes because amino derivatives are included in the basic entities.
