Does Gelatine intake increase B6 requirements?

The following is taken from Nutrient Reference Values for Australia and New Zealand:

"The amino acid tryptophan is converted to nicotinamide with an average conversion efficiency of 60:1."

"It has been proposed that vitamin B6 requirements may be increased at higher protein intake (Baker et al 1964, Hansen et al 1996a, Linkswiler 1978), although other studies have not shown this (Pannemans et al 1994). Nevertheless, protein intake is generally taken into consideration in setting requirements for vitamin B6."

"Indicators used to assess requirements have ranged from measures of ... <part skipped> ...tryptophan metabolites."
.

Most foods rich in protein (one of the amino acids being tryptophan) are rich in B6 as well.

Gelatine does neither contain tryptophan nor B6. Do I need to balance the lack of B6? Could tryptophan be the reason for the proposed increase of B6 requirement?

Does anyone know?

Would I better supplement B6 when a considerable amount of my protein intake comes from gelatine?
